Dogen (1200-1253)

Late, hagiographic biographical sources

Unlike a canonised saint whose trial preserves depositions and archival records, Dōgen's life is known only through biographies written after his death, with an edifying purpose as much as a historical one. The two main ones are the Kenzeiki (建撕記), compiled in the fifteenth century by the monk Kenzei on the basis of earlier monastic traditions, and the Denkōroku ("Record of the Transmission of the Light"), written in the early fourteenth century by Keizan Jōkin, fourth patriarch of the school. These texts, written two to three centuries after the events, blend reliable chronology with legendary elements typical of the Japanese Buddhist hagiographic genre^[2].

The document closest to the events remains Dōgen's own personal journal, the Hōkyōki (寶慶記), kept during his stay in China between 1225 and 1227, which records day by day his exchanges with his master Rujing. It is the most reliable source for reconstructing the decisive experience of his awakening, and it is the one modern scholarly studies use to distinguish the historical core from later hagiographic amplification^[3].

The Shōbōgenzō, a work composed over twenty years and rediscovered in the twentieth century

The Shōbōgenzō (正法眼蔵, "Treasure of the True Dharma Eye") is not a unified treatise but a collection of fascicles — from 75 to 95 depending on the edition — written over about twenty years, from 1231 until Dōgen's death in 1253, then completed and reorganised by his disciples. Remarkably for the time, Dōgen wrote it in Japanese rather than in classical Chinese, the learned language in which most literate Buddhist literature was then expressed^[4].

The work remained little circulated for centuries, reserved to a restricted circle of Sōtō school specialists, partly because his successor Keizan Jōkin reoriented the tradition toward popular religious practices rather than toward the philosophical deepening of its founder. Only after the Meiji Restoration (1868), and above all thanks to the work of the philosopher Watsuji Tetsurō published between 1926 and 1935, did the Japanese general public rediscover Dōgen — seven centuries after his death^[5]. The most widely cited English translation of reference today is the one edited by Kazuaki Tanahashi, Moon in a Dewdrop: Writings of Zen Master Dōgen (San Francisco, North Point Press, 1985), which gathers the fascicles most studied in the West^[6].

An Aristocratic Birth and a Bereavement That Awakens the Sense of Impermanence

Dōgen was born on 26 January 1200 in Kyōto, into a branch of the high court aristocracy: his mother, Ishi, was the daughter of the imperial regent Fujiwara (Matsudono) Motofusa, while his paternal ancestry remains debated between two figures of the nobility, Minamoto no Michichika and his son, the poet Michitomo^[7]. This genealogical uncertainty, common in medieval religious biographies where birth is reinterpreted after the fact in light of the figure's later sanctity, does not affect the best-established facts: the gilded childhood, then the early bereavement.

Around 1207, when he was seven or eight years old, Dōgen lost his mother. On her deathbed, she is said to have asked him to abandon the court career for which his rank destined him in order to enter holy orders^[8]. Traditional biographers see in this bereavement the origin of his acute awareness of impermanence (mujō 無常), a theme that runs through all his later work — to the point that the Busshō fascicle of the Shōbōgenzō would go so far as to identify impermanence itself with Buddha-nature, as will be seen below.

Ordination on Mount Hiei and the Fundamental Doubt About Original Awakening

In 1213, at thirteen, Dōgen climbed Mount Hiei, seat of the Enryaku-ji monastery and nerve center of the Tendai school, then dominant in learned Japanese Buddhism; there he was trained under the direction of his maternal uncle, the monk Ryōkan Hōgen^[9]. Yet Tendai teaching professes the doctrine of original awakening (hongaku 本覚): all beings already possess buddhahood by nature. Dōgen drew from it a question that would never leave him, known in the tradition as the "great doubt": if all beings are already awakened by nature, why did the buddhas of the three times seek awakening and practice asceticism?^[10]

Biographies report that Dōgen questioned several Tendai masters on this point without receiving a satisfactory answer, which hastened his growing dissatisfaction with a clergy he judged too absorbed in court intrigues and in the decline of monastic rigor^[11]. This dissatisfaction drove him away from Mount Hiei, in search of a teaching that better articulates practice and awakening — a quest that would structure his entire later life.

The Meeting with Eisai and Myōzen at Kennin-ji

In 1217, Dōgen entered Kennin-ji, the Kyōto temple founded by Myōan Eisai (1141-1215), the monk who had introduced the Rinzai school of Zen to Japan after his own travels to China. Eisai having died two years earlier, Dōgen trained under the direction of his successor, Myōzen (1184-1225)^[12]. It was at Kennin-ji that Dōgen had his first sustained experience of Zen practice properly speaking, distinct from Tendai rites and scholastic learning.

After several years of training, Myōzen and Dōgen decided together to cross the sea to seek, in China itself, a teaching they judged closer to the source. This choice was not a trivial one: in the thirteenth century, the voyage to the continent remained perilous, reserved for a handful of determined monks, and meant abandoning, potentially for good, the relative comfort of a great monastery in the capital.

The crossing to Song China and the cook of Mount Ayuwang

In 1223, Dōgen and Myōzen embark for Song China^[13]. An episode that occurred shortly after their arrival, while they were anchored in the port of Qingyuan (present-day Ningbo), left a lasting mark on Dōgen: a monk in his sixties, cook (tenzo) of the monastery of Mount Ayuwang, came aboard to buy dried Japanese mushrooms. Surprised that a man of that age held so modest a function as cooking rather than devoting himself to the study of ancient texts, Dōgen asked him:

"Venerable tenzo, why do you not devote yourself to the practice of zazen and to the study of the words of the ancient masters, rather than troubling yourself by holding the office of cook and working in this way?" — Dōgen, reporting his question to the cook of Mount Ayuwang, Tenzo Kyōkun^[14]

The old monk answered him, with a firmness that disconcerted the young Japanese, that he did not yet understand what words truly are nor what practice truly is, and invited him to come and discuss it at Ayuwang monastery. A few months later, during a second meeting, he clarified his thought:

"If you want to understand words, you must examine what words are. If you want to practice, you must understand what practice is." — The cook of Mount Ayuwang, as reported by Dōgen, Tenzo Kyōkun^[15]

This exchange, seemingly minor, would become for Dōgen a doctrinal cornerstone: the humblest tasks of monastic life — cooking, sweeping, washing one's face — are not subordinate activities preparing for the "true" seated practice, but a form of practice itself in its own right. Years later, he would draw from it an entire treatise, the Tenzo Kyōkun ("Instructions to the Cook," 1237)^[16].

Tiantong Rujing: "dropping off body and mind"

After visiting several Chan monasteries without finding the teaching he was seeking, Dōgen settled in 1225 with Tiantong Rujing (天童如淨, 1163–1228), a master of the Caodong (曹洞) school, at Tiantong monastery near Ningbo^[17]. Rujing struck him as a master of rare exactingness and uprightness, free of the worldly compromises that Dōgen had reproached the Tendai clergy of Kyōto for^[18].

The founding episode of the relationship between the two men is recounted by Dōgen himself in his journal, the Hōkyōki: during a night-time zazen session, Rujing severely rebuked a drowsy monk, calling out to him:

"The study of Zen is dropping off body and mind. Why do you give yourself over to sleep?" — Tiantong Rujing, as reported by Dōgen, Hōkyōki^[19]

Upon hearing this formula — shinjin datsuraku (身心脱落), "body and mind dropped off" — Dōgen reports having undergone a decisive experience of liberation. Rujing, consulted, confirmed the authenticity of this experience and, in 1227, formally transmitted to him the Dharma of the Caodong lineage, making Dōgen the first master to bring this transmission back to Japan^[20]. Myōzen having died in China as early as 1225, Dōgen returned to Japan alone, bearing the relics of his travelling companion and a teaching he now judged authentic.

The return to Japan and the founding of Kōshōji

Back at Kennin-ji in 1227–1228, Dōgen almost immediately wrote the Fukanzazengi (普勧坐禅儀, "Universally Recommended Principles for Seated Practice"), a brief manual that opens with a programmatic assertion:

"Now, when examined closely, the Way is fundamentally perfect and universally present. How could it depend on practice and realisation?" — Dōgen, Fukanzazengi (c. 1227–1228)^[21]

This sentence already condenses what would become the heart of his doctrine: if awakening is already perfectly present in all reality, practice is not a means of acquiring something that is lacking, but the very expression of what is already accomplished. In 1230, under growing pressure from the established Tendai clergy, hostile to the spread of an autonomous Zen teaching in the capital, Dōgen left Kyōto to settle in Uji, then in 1233 founded a small temple on a family estate, which he enlarged and named Kannondōri Kōshōhōrin-ji (Kōshōji)^[22]. It was the first temple built in Japan according to Chinese monastic architecture and usages — an ordination courtyard, a collective meditation hall (sōdō), and a strict communal rule of life.

The break with Tendai and the exile to Echizen

Kōshōji quickly attracted disciples, including Kōun Ejō (孤雲懐奘, 1198–1280), who joined the community in 1234 and would become Dōgen's successor^[23]. But tensions with the Tendai establishment of Kyōto, jealous of its religious monopoly and hostile to the growing institutional autonomy of Zen, intensified to the point of threatening the community's survival. In 1243, Dōgen accepted the invitation of the feudal lord Hatano Yoshishige, converted to his teachings, and transferred his community to the distant province of Echizen, on the western coast of Japan, far from the influence of the capital^[24].

This move, apparently a retreat, in fact corresponded to a deliberate choice: to withdraw from court intrigues and the compromises needed for survival in the capital, in order to found, in an austere mountain setting, a monastic community faithful to the Chinese usages he had known under Rujing.

The founding of Eihei-ji

Settled first in a provisional temple, Daibutsu-ji, Dōgen renamed it in 1246 Eihei-ji (永平寺, "Temple of Eternal Peace")^[25]. The name, which refers to the Chinese Yongping era (永平, 58–75 AD) under which Buddhism is said to have been introduced into China, asserts the claimed continuity between the Chinese Chan tradition and the newly founded monastery. There Dōgen established a monastic rule of life of meticulous rigour — codified notably in the Eihei Shingi ("Rules of Purity of Eihei-ji") — which organises even the smallest gestures of communal life: posture for sleeping, the manner of dressing, the way of eating in silence in the refectory (ōryōki), everything becoming an occasion for practice.

Eihei-ji remains today, alongside Sōji-ji (founded later by Keizan Jōkin), one of the two head temples (honzan) of the Sōtō school, which now numbers nearly fourteen thousand temples spread across the whole of Japan^[26].

The invitation of the regent Hōjō Tokiyori to Kamakura

In 1247, the regent of the Kamakura shogunate, Hōjō Tokiyori, invited Dōgen to the military capital to receive lay ordination from him and Buddhist teachings^[27]. Dōgen went there, but returned to Eihei-ji as early as 1248, without having accepted the offers of patronage and of founding a temple at Kamakura that the military power seems to have proposed to him. This refusal, reported by the biographical tradition, is consistent with the whole of his teaching: proximity to power, however benevolent, carried for him the risk of compromising the purity of the monastic practice he had founded far from any court.

Illness and death in Kyōto

In the autumn of 1252, Dōgen's health declined gravely. He transmitted his robes and his office as abbot to Kōun Ejō, making him the second master of Eihei-ji^[28]. In the spring of 1253, in the hope of finding a remedy, he undertook the journey to Kyōto, where he died on 22 September 1253, aged fifty-three. Tradition attributes to him a final poem (jisei), composed shortly before his death:

"Fifty-four years illuminating the sky. / A final trembling leap that shatters a billion worlds." — Death poem (jisei) attributed to Dōgen, 1253^[29]

Zazen as a practice in itself, not as a means

The heart of Dōgen's teaching is the practice he calls shikantaza (只管打坐), literally "only, precisely, sitting". Unlike discursive meditation on an object, or the progressive resolution of a kōan — the method favoured by the rival Rinzai school — shikantaza aims at no goal outside itself: neither vision, nor extinction of the mind, nor the resolution of a riddle. The practitioner sits, in full- or half-lotus posture, facing a wall, and lets thoughts arise and vanish without clinging to them or pushing them away^[30].

This apparent absence of content does not mean an absence of mental discipline. Dōgen describes a state he calls hishiryō (非思量), "non-thinking", distinct both from discursive thought and from the mere absence of thought:

"Sit firmly, think the unthought. How does one think the unthought? Through non-thinking. This is the essential art of zazen." — Formula attributed to Dōgen in the later recensions of the Fukanzazengi and in the Shōbōgenzō Zazengi^[31]

The unity of practice and verification

On this foundation Dōgen builds his most original doctrinal contribution, resolving in his own way the "great doubt" that had tormented him on Mount Hiei. If the practice of zazen aimed at a future awakening, distinct from itself, it would fall back into the same logical difficulty he reproached the Tendai school with: why seek what is already given? Dōgen answers by affirming the radical identity of practice and the verification of awakening (shushō-ittō, 修証一等):

"In the Buddha Dharma, practice and verification are identical. [...] Because it is a practice grounded in verification, the beginner's quest for the Way is the substantial totality of original verification." — Dōgen, Bendōwa [On the Practice of the Way], 1231^[32]

In other words, awakening is neither a distant goal toward which practice would progress step by step, nor an already-acquired state that would render practice superfluous: to sit in zazen is, in the very instant, the actualisation of Buddha-nature, not its preparation. This solution, far from being a simple rejection of the Tendai doctrine of original awakening he had received on Mount Hiei, constitutes a radical reformulation of it: the question is no longer whether one already possesses Buddha-nature, but how this possession is actualised concretely, here, in the seated body^[33].

Universal Buddha-nature

In the Busshō fascicle of the Shōbōgenzō, Dōgen pushes the traditional doctrine of Buddha-nature (busshō 仏性, Sanskrit tathāgatagarbha) to its most radical consequences. Whereas the Indian tradition reserved this nature for sentient beings, Dōgen extends it to the totality of being:

"The very impermanence of grass and tree, thicket and forest, is Buddha-nature." — Dōgen, Shōbōgenzō, Busshō fascicle^[34]

This formula overturns the usual reading according to which Buddha-nature would be a permanent principle hidden beneath the apparent impermanence of things: for Dōgen, it is impermanence itself, as such, that is Buddha-nature — not an immutable substrate behind change, but change itself as ultimate manifestation^[35]. This identification has immediate consequences for a reader schooled in the Catholic metaphysics of substance and nature, as will be seen in the final part of this article.

Being-time, a philosophy of the present

The Uji fascicle ("Being-Time") develops a reflection on time that several twentieth-century Western philosophers have compared to that of Heidegger in Sein und Zeit^[36]. For Dōgen, time is not an external container in which beings would succeed one another: each being is its own time, each instant is a totality of being that extends into no other. This conception, difficult to translate into Western categories of linear time, aims to cut short any representation of awakening as a future toward which one would progress: if each instant is already the totality of being-time, awakening cannot be deferred to a later instant.

Studying the self in order to forget it, according to the Genjokoan

The opening fascicle of the Shōbōgenzō, Genjōkōan ("The Actualised Realisation of the kōan"), contains the most frequently quoted formula in all of Dōgen's work:

"To study the Buddha Way is to study the self. To study the self is to forget oneself. To forget oneself is to be verified by the ten thousand things. To be verified by the ten thousand things is to cast off the body and mind of oneself and the body and mind of others." — Dōgen, Shōbōgenzō, Genjōkōan fascicle (1233)^[37]

This passage sums up the spiritual trajectory Dōgen proposes: not the affirmation of a self that would seek awakening as a possession, but a progressive stripping away of the self itself until its disappearance in the immediate experience of things — a stripping away he designates elsewhere by the formula already encountered, shinjin datsuraku, "body and mind fallen away"^[38].

Daily life as the Way, according to the Tenzo Kyokun

Faithful to the lesson received from the old cook of Mount Ayuwang, Dōgen wrote in 1237 the Tenzo Kyōkun, a treatise devoted to the seemingly subordinate function of monastic cook. In it he explains that preparing rice and soup for the community, carried out with unreserved attention and care, is not a preparatory task for the "true" practice of zazen, but practice itself in its most concrete form^[39]. This insistence on the sacredness of the ordinary gesture — cooking, sweeping, dressing — runs through the whole Shōbōgenzō and constitutes one of the most characteristic traits of the spirituality Dōgen bequeathed to the Sōtō school: a way that never separates contemplation from the humblest manual action.

Kōun Ejō and the succession dispute at Eihei-ji

Upon Dōgen's death, Kōun Ejō succeeded him as second abbot of Eihei-ji. But the following generation experienced a serious succession crisis: Ejō retired in 1267 in favor of Tettsū Gikai, who introduced into the monastery's practice elements borrowed from Shingon and Tendai esotericism, provoking opposition from part of the community attached to the purity of Dōgen's teaching. Ejō resumed the abbacy in 1272; after his death in 1280, Gikai became abbot again with the support of local military protectors, before finally being forced to leave the temple. His successor, Gien, then restored Dōgen's doctrinal orthodoxy at Eihei-ji^[40].

Keizan Jōkin, the "second founder," and popular diffusion

It was another disciple in Gikai's lineage, Keizan Jōkin (瑩山紹瑾, 1268–1325), who ensured the massive spread of the Sōtō school throughout Japanese society. Founder in 1321 of the monastery of Sōji-ji, he is traditionally honored, alongside Dōgen, as the "second founder" (taiso) of the school — Dōgen receiving the title of kōso, "high founder"^[41]. While Dōgen addressed himself principally to a literate monastic elite, Keizan integrated elements of popular devotion (funerary rites, protective cults, incorporation of local deities), which largely explains the considerable expansion of the Sōtō school in the Japanese countryside in the 14th–16th centuries — at the cost, according to some historians, of a relative departure from Dōgen's original philosophical rigor^[42].

The Sōtō school today

Today, the Sōtō school, administered jointly from Eihei-ji and Sōji-ji, claims some fourteen thousand temples on Japanese territory, making it the largest of the country's monastic Buddhist schools by number of establishments^[43]. The Shōbōgenzō, long reserved for a restricted circle of specialists, is now taught in Japanese Buddhist universities and translated in full into English, French, and German^[44].

The modern rediscovery by Watsuji Tetsurō

The Japanese philosopher Watsuji Tetsurō (1889–1960) published between 1926 and 1935 a series of studies that brought Dōgen out of the relative monastic obscurity in which he had remained for seven centuries, making him known for the first time to the broader literate Japanese public^[45]. Watsuji stayed in Berlin from April 1927 and there discovered the recent publication of Martin Heidegger's Being and Time; his later work Fūdo (Climate and Culture) develops, partly on the basis of his reading of Dōgen, a critique of Heidegger's emphasis on temporality at the expense of the spatiality of existence^[46].

A debated affinity with Heidegger

Since Watsuji, many Western scholars have drawn parallels between Dōgen's reflection on being-time (uji) and the Heideggerian analysis of Dasein as being-toward-death inscribed in temporality^[47]. This comparison, fruitful for situating Dōgen in the history of world philosophy, must nevertheless be handled with caution: as the reference academic survey notes, very few points remain on which a genuine scholarly consensus exists concerning Dōgen's thought, and the comparison with Heidegger remains a matter of debate among specialists rather than an established equivalence^[48].

Zen in the United States and the rise of mindfulness meditation

In the 20th century, several Sōtō masters emigrated to the United States and founded centers there that became major hubs for the spread of Zen in the West — the best known being Shunryu Suzuki (1904–1971), who arrived in San Francisco on 23 May 1959 to lead Sōkō-ji temple, then founded the San Francisco Zen Center in 1962, whose teaching directly takes up Dōgen's shikantaza^[49]. This American, then European, diffusion of Sōtō Zen constitutes one of the channels through which seated meditation techniques, secularized and detached from their original Buddhist doctrinal framework, fed from the 1970s–1980s onward the contemporary programs of so-called "mindfulness" meditation (mindfulness).

Christian Zen: Father Enomiya-Lassalle and the theological debate

The encounter between Dōgen's teaching and Christianity was not limited to an abstract philosophical dialogue: in the 20th century it took the form of a concrete attempt at assimilation by Catholic religious. The German Jesuit Hugo Makibi Enomiya-Lassalle (1898–1990), a missionary in Japan from 1929 and gravely wounded in the atomic bombing of Hiroshima on 6 August 1945, began the practice of Zen in 1956 under the direction of Master Harada Daiun Sōgaku, then of Yamada Kōun, who granted him in the late 1960s the title of rōshi (Zen master) while knowing him to be faithful to his Christian faith^[50]. He published several works on the possibility, as he saw it, of integrating the practice of zazen into Christian prayer, without losing its own identity^[51].

This attempt, undertaken in the broader wake of the interreligious dialogue called for by the Second Vatican Council, provoked within the Church a serious theological debate on the limits of such an integration — a debate that would lead, in 1989, to an explicit doctrinal intervention by the Congregation for the Doctrine of the Faith, discussed in the final part of this article.

What the Church can acknowledge: rigor, detachment, the quest for truth

The Second Vatican Council, in its declaration Nostra Aetate on the relations of the Church with non-Christian religions (28 October 1965), lays down the principle that must govern every Catholic judgment made about a non-Christian spiritual tradition:

"The Catholic Church rejects nothing that is true and holy in these religions. She regards with sincere reverence those ways of conduct and of life, those precepts and teachings which, though differing in many aspects from what she holds and sets forth, nonetheless often reflect a ray of that Truth which enlightens all men." — Ecumenical Council Vatican II, Nostra Aetate, § 2^[52]

The same paragraph explicitly names Buddhism, of which Dōgen's Zen constitutes a historical branch:

"In Buddhism, according to its various forms, the radical insufficiency of this changing world is recognized and a way is taught by which men, with a devout and trusting heart, may acquire the state of perfect liberation." — Ecumenical Council Vatican II, Nostra Aetate, § 2^[53]

In the light of this principle, the Church can recognize in Dōgen a genuine and fruitful intuition: an acute awareness of the impermanence of all created things, the refusal to dissociate contemplation from ordinary life — working, cooking, sweeping, as so many occasions for attentive presence — and an ascetic exactingness that led a court aristocrat to abandon everything for a truth he judged superior to his own comfort. These traits, without being in themselves supernatural in the theological sense of the term, belong to what the patristic tradition called the "seeds of the Word" (semina Verbi) scattered throughout the whole of humanity, which the Second Vatican Council explicitly takes up again in its decree Ad Gentes on the missionary activity of the Church^[54].

The Magisterium's 1989 Warnings on Eastern Meditation

The experience of Father Enomiya-Lassalle and other Catholic religious who integrated elements of Zen practice into their spiritual life led the Congregation for the Doctrine of the Faith, then headed by Cardinal Joseph Ratzinger, to publish on 15 October 1989 a letter to the bishops of the Catholic Church, Orationis Formas, devoted to certain aspects of Christian meditation. This text, without condemning on principle the borrowing of certain Eastern methods, sets precise doctrinal limits on it.

The document first warns against the risk of substituting for the "saving works of God" — that is, for the concrete history of biblical Revelation and the person of Christ — the search for an indeterminate and impersonal absolute:

"[Certain forms of prayer tend to] abandon not only meditation on the saving works accomplished in the history of salvation by the God of the Old and New Covenant, but even the thought of the one God in three Persons, who is love, in order to 'plunge' into 'the indeterminate abyss of the divinity': this is a mode of prayer foreign to Christianity." — Congregation for the Doctrine of the Faith, Orationis Formas, 15 October 1989, § 12^[55]

The text then explicitly warns against the temptation to place on the same level the impersonal absolute aimed at by certain Buddhist paths and the personal Trinitarian God of Christian Revelation, and it recalls that the physical sensations produced by certain bodily concentration exercises must never be confused with the authentic spiritual consolations given by the Holy Spirit:

"Certain physical exercises automatically produce sensations of quiet and relaxation, gratifying feelings, and even phenomena of light and warmth that resemble spiritual well-being. To take these for authentic consolations of the Holy Spirit would be a totally erroneous way of conceiving the spiritual journey." — Congregation for the Doctrine of the Faith, Orationis Formas, 15 October 1989, § 28^[56]

Finally, the letter recalls a fundamental anthropological truth that any form of absorption mysticism — which several currents of Zen Buddhism, including certain readings of Dōgen's shinjin datsuraku as a total dissolution of the self, may approach — risks contradicting: even in the highest degree of mystical grace, the human person created by God is never absorbed or dissolved into the divine, but remains, united to God, herself^[57].

An Impersonal Buddha-Nature, Not a Personal and Revealed Trinitarian God

The most radical difference between Dōgen's doctrine and the Catholic faith concerns the very nature of ultimate reality. For Dōgen, busshō, Buddha-nature, is neither a person nor a creator distinct from the world whom he would have brought into existence by a free act of love: it is immanent in all things, identified with impermanence itself, without will, without word, without a relation of love toward creatures^[58]. Catholicism professes on the contrary a One and Triune God, personal, who reveals himself freely in history, speaks to his creatures, loves them with a love that precedes them and calls them by name (Is 43:1) — a difference that the Catechism of the Catholic Church summarizes by recalling that grace is "a participation in the life of God himself" which "introduces us into the intimacy of Trinitarian life"^[59], participation in a personal relationship, not absorption into an impersonal principle.

Neither Creation, Nor Sin, Nor Grace, Nor Resurrection of the Flesh

From this fundamental difference flows a series of irreducible doctrinal divergences. Dōgen's Zen knows no doctrine of the creation of the world by a free and good God; it therefore has no doctrine of original sin either, as a rupture of a covenantal relationship with a personal Creator — the obstacle to awakening being rather attachment and the illusion of a separate self, not an inherited moral fault binding all humanity before God. Correspondingly, the Sōtō school knows neither a doctrine of grace as a gratuitous and supernatural gift of a God who takes the initiative of salvation, nor a doctrine of the Incarnation of a Saviour who assumes human nature in order to redeem it from within: awakening, in Dōgen, is obtained through the actualization of one's own Buddha-nature in zazen, not through the reception of a salvation offered from without by grace.

Finally, the eschatological promise of Sōtō Zen — liberation from illusion and suffering through the extinction of attachment to the separate self — differs radically from the Christian hope of the resurrection of the flesh, which promises not the dissolution of the individual self into an impersonal absolute, but the definitive glorification, by grace, of the whole human person, body and soul reunited, in eternal communion with the personal God who created and loved her from all eternity.

Seeds of the Word and Fulfilment in Christ

As with Confucius and with the Buddha^[60], the Catholic position toward Dōgen is therefore neither contemptuous rejection nor syncretistic assimilation that would erase the real differences. The conciliar decree Ad Gentes invites us to discern, in the religious traditions of humanity, "seeds of the Word" (semina Verbi) — taken up from the patristic doctrine of Saint Justin and Saint Irenaeus — called to be purified and fulfilled in Christ, not merely juxtaposed to him as equivalent paths^[61]. Dōgen's ascetic rigour, his attention to impermanence, his conviction that the sacred is not separate from the most everyday gesture, are, in this sense, real intuitions that the Church can honour without thereby silencing what separates them radically from the Revelation received in Jesus Christ: a God who is not an impersonal principle to be reached through silent sitting, but a Person who, first, came to sit beside man.
