The 1983 Code of Canon Law (Codex Iuris Canonici)

The surprise announcement of John XXIII (25 January 1959)

Barely three months after his election, John XXIII gathered the 25 January 1959 the seventeen cardinals present in Rome, in the chapter hall of the abbey of Saint Paul Outside the Walls, at the close of the octave of prayer for Christian unity.^[9] Before a small assembly, he announced, in the very words of the allocution, a twofold celebration that took everyone by surprise: a synod of the diocese of Rome and an ecumenical council — the future Vatican II — whose celebration, he immediately added, "would happily lead to the wished-for and awaited aggiornamento of the Code of Canon Law". The "aggiornamento" of the Code is thus presented by John XXIII as the expected fruit of the two assemblies, not as a third, autonomous announcement.^[10][11]

The allocution delivered that day clearly states the scope of these projects:

« Nous prononçons devant vous, certes en tremblant un peu d'émotion, mais en même temps avec une humble résolution de propos, le nom et la proposition de la double célébration : d'un Synode diocésain pour la Ville, et d'un Concile œcuménique pour l'Église universelle. […] Elles conduiront heureusement à l'aggiornamento souhaité et attendu du Code de droit canonique. » — Jean XXIII, allocution Questa festiva ricorrenza, salle capitulaire de l'abbaye Saint-Paul-hors-les-Murs, 25 janvier 1959 (traduction Ignispedia de l'italien)^[12]

The order of the projects is significant. For John XXIII, the Code was not to precede the council — it was to follow it. The revision of canon law would not be an isolated technical act, but the juridical translation of a new gaze of the Church upon herself, which the council would have formulated.^[13][14]

A long wait: from the council to the Code

The council lasted four autumn sessions, from 11 October 1962 to its closure on 8 December 1965, and produced sixteen documents, including four major constitutions: Sacrosanctum Concilium (liturgy), Lumen Gentium (the Church), Dei Verbum (Revelation), Gaudium et Spes (the Church in the modern world).^[15] By the time the 1917 Code actually began to be rewritten, it was on these constitutions — above all Lumen Gentium — that canonists henceforth had to rely.

But why wait twenty-four years between the announcement and the promulgation? The answer comes down to three words: continuity, recasting, consultation. Continuity, because it was less a matter of inventing a law than of recasting the existing one — most of the 1917 canons passed, amended, into the 1983 Code. Recasting, because the new ecclesiological principles (People of God, collegiality, communion) could not simply be grafted onto the old architecture without rethinking it. Consultation, because the commission submitted its drafts to every episcopate in the world, on several occasions, exactly as Gasparri had done in 1912-1914.^[16][17]

Another, deeper reason justified the wait: the Code must not be promulgated until it had truly absorbed conciliar ecclesiology, lest the theological work in progress be prematurely frozen. Paul VI's motu proprio Causas matrimoniales (1971) moreover showed that urgent reforms — for instance in matrimonial nullity procedure — could be anticipated by particular laws, without waiting for the Code itself.^[18]

The Pontificia Commissio (28 March 1963)

On 28 March 1963, John XXIII officially established the Pontificia Commissio Codici Iuris Canonici Recognoscendo — the "Pontifical Commission for the Revision of the Code of Canon Law". Chaired first by Cardinal Pietro Ciriaci (1885-1966) and then, after his death, by Cardinal Pericle Felici (1911-1982) — the former secretary general of the council — it comprised a hard core of canonists and was widened over the years to bishops, religious, lay people and observers from the Eastern Churches.^[19][20]

When Felici died in March 1982, one year before the promulgation, he was replaced at the head of the commission by the Venezuelan Cardinal Rosalio José Castillo Lara (1922-2007), a Salesian, who had been its secretary and who brought the project to completion.^[21]

The Principia (1967): ten guiding principles

Before writing a single canon, the commission first asked the whole Church: "On which principles do you want us to work?" In 1967, it therefore published, under the title Principia quae Codicis Iuris Canonici recognitionem dirigant, ten guiding principles which were submitted to the synod of bishops of October 1967, which approved them by an overwhelming majority.^[22][23]

These ten principles frame the entire revision. Here they are in full, in the order of the document (Communicationes 1 (1969), pp. 77-85):

These principles — above all the 5th, 7th and 8th — fundamentally distinguish the 1983 Code from its 1917 ancestor, which remained more centred on hierarchical authority and less on the rights of the faithful. The Church of the faithful has become the subject of the law, and no longer merely its object.^[24]

Eleven coetus and thousands of canonists

The commission worked in eleven specialised working groups (coetus studiorum) each covering one field: general norms, People of God, magisterium, sacraments, temporal goods, sanctions, trials, and so on. Each group brought together some ten consultors chosen from all over the world — bishops, professors of canon law, judges of the Roman Rota, secretaries of dicasteries.^[25]

The undertaking was considerable. In Rome, the secretariat — where Msgr Willy Onclin (1905-1989), professor at Louvain, served as adjunct secretary — centralised the schemata (draft canons) and reworked them many times in the light of the observations received.^[26]

A universal consultation (1972-1982)

As in 1912, the commission submitted its drafts to the universal episcopate, to the ecclesiastical faculties of canon law, to the major superiors of religious institutes and to the dicasteries of the Curia. The consultation unfolded in waves, over a decade:

The animadversiones — observations sent by bishops, episcopal conferences, faculties and religious the world over — number in the thousands: the 1981 Relatio summarising them runs to 358 pages alone, reprinted in Communicationes 14-16 (1982-1984). Each was classified, analysed and, for many, incorporated. This work of discernment is probably the widest juridical consultation ever conducted in the history of the Church.^[27][28]

Sacrae Disciplinae Leges

On 25 January 1983 — a date carefully chosen for its symbolism: it was both the feast of the Conversion of Saint Paul and the twenty-fourth anniversary to the day of John XXIII's announcement — John Paul II promulgated the new Code by the apostolic constitution Sacrae Disciplinae Leges.^[29]

The text is short but of immense scope. It recalls the genesis of the Code, John XXIII's decision, the role of the council, the work of the commission. Then it situates juridically the scope of the act:

« C'est pourquoi, en vertu de l'autorité suprême dont je suis investi, par cette Constitution destinée à valoir à l'avenir, je promulgue le présent Code, tel qu'il a été ordonné et révisé. J'ordonne qu'il ait force de loi pour toute l'Église latine à partir du premier dimanche de l'Avent de cette année 1983. » — Jean-Paul II, constitution apostolique Sacrae Disciplinae Leges, 25 janvier 1983 (traduction française)^[30]

The choice of the first Sunday of Advent as the date of entry into force echoes that of Pentecost Sunday by Benedict XV in 1918: a liturgical beginning for a juridical beginning. Advent is the waiting for Christ, the season of conversion; it says that canon law has no other end than to prepare the soul for the coming of the Lord.^[31]

The Code as the extension of the council

The central conceptual contribution of Sacrae Disciplinae Leges is to present the Code as the juridical extension of Vatican II. The most quoted formula is this one:

« Ce nouveau Code pourrait être compris comme un grand effort pour traduire en langage canonique cette même doctrine, c'est-à-dire l'ecclésiologie conciliaire. Et si l'on ne peut transposer parfaitement dans le langage canonique l'image de l'Église décrite par la doctrine du Concile, néanmoins, à cette image, le Code doit toujours se référer comme à son modèle primordial, dont il doit exprimer, autant qu'il est possible, par sa nature même, les lignes. » — Jean-Paul II, constitution apostolique Sacrae Disciplinae Leges, 25 janvier 1983 (traduction française)^[32]

The idea is new, and it has a practical consequence: the 1983 Code cannot be understood on its own. It needs to be read together with the texts of Vatican II; and certain canons (for example canon 204 § 1, which defines who is christifidelis — a faithful of Christ) are almost verbatim paraphrases of conciliar passages (Lumen Gentium, n. 31).^[33][34]

Five purposes of canon law

The same constitution sets out the five purposes the new Code must serve in the life of the Church, in a page that has remained famous:

« Le Code apparaît donc comme un complément nécessaire de l'enseignement du Concile […]. Le but du Code n'est en aucune façon de remplacer la foi, la grâce, les charismes et surtout la charité dans la vie de l'Église ou des fidèles. Au contraire, il a plutôt pour but de créer dans la société ecclésiale un tel ordre que, donnant la première place à l'amour, à la grâce, aux charismes, il facilite en même temps leur développement organique dans la vie tant de la société ecclésiale que de chacun des fidèles. » — Jean-Paul II, constitution apostolique Sacrae Disciplinae Leges, 25 janvier 1983 (traduction française)^[35]

The order of priorities is exact: grace first, law second. That is the great difference with the temptation of a juridicism that would take law for an end in itself. The Code has meaning only as a servant of ecclesial communion.

From the Roman plan (1917) to the Trinitarian plan (1983)

The 1917 Code — 2,414 canons in five books — heir to the Roman jurist Gaius (personae / res / actiones), structured its three central books around the three classical axes of Roman jurisprudence: persons (Book II, De personis), things (Book III, De rebus), actions (Book IV, De processibus), framed by the general norms (Book I) and penal law (Book V, De delictis et poenis). The 1983 Code abandons this Latin plan for a more theological scheme, articulated around the three offices of Christ (tria munera Christi): to sanctify (munus sanctificandi), to teach (munus docendi), to govern (munus regendi) — offices entrusted to the whole Church, and exercised in a particular way by the hierarchy. It is the ecclesiology of Lumen Gentium that inspires this plan.^[36][37]

The seven books at a glance

Here is how the 1,752 canons of the 1983 Code are distributed:

Several shifts are significant. Book II (De Populo Dei) places the faithful — and no longer clerics alone — at the heart of the Code, beginning with the rights and duties common to all the baptised (canons 208-223). Book III detaches the teaching office, formerly scattered through the 1917 De rebus, to make it a whole book — a sign that the Word and catechesis are not one "thing" among others. Book IV gathers together all sacramental and liturgical law. Book VII, finally, centralises all judicial procedures.^[38]

1,752 canons: fewer, and different

The 1983 Code counts 1,752 canons, against 2,414 in the 1917 Code. The apparent decrease — about 28% — does not mean impoverishment. Many old canons, which minutely described situations now dealt with in particular laws (statutes of the episcopal conferences, Pastor Bonus for the Curia, Universi Dominici Gregis for the conclave), were removed. Conversely, matters absent from the 1917 Code (fundamental rights of the faithful, structures of communion, episcopal conferences) find their place in it.^[39][40]

Canon 204: who is the subject of canon law?

Canon 204 § 1 opens Book II. It defines with precision who is christifidelis — a faithful of Christ — and it does so in terms borrowed from Lumen Gentium:

« Les fidèles du Christ sont ceux qui, en tant qu'incorporés au Christ par le baptême, sont constitués en peuple de Dieu et qui, pour cette raison, faits participants à leur manière à la fonction sacerdotale, prophétique et royale du Christ, sont appelés à exercer, chacun selon sa condition propre, la mission que Dieu a confiée à l'Église pour qu'elle l'accomplisse dans le monde. » — Codex Iuris Canonici (1983), canon 204 § 1^[41]

This canon is a silent revolution. The primary subject of canon law is no longer the cleric, but the faithful, baptised, of whom lay people form the immense majority. It is on this basis that the Code then sets out a list of rights and duties common to all the faithful (canons 208-223) which had no equivalent in 1917, and in which one finds for example the duty to proclaim the message of salvation, the right to receive the sacraments, or the freedom to found associations.^[42][43]

The place of the laity: canons 224-231

Canons 224 to 231 (Book II, Part I, Title II) deal specifically with lay people, and reverse the old clerical focus of the 1917 Code, which spoke almost exclusively of clerics. Canon 225 § 2 expressly recognises the mission of lay people in the temporal order:

« Chacun selon sa propre condition, ils sont aussi tenus au devoir particulier d'imprégner d'esprit évangélique et de parfaire l'ordre temporel, et de rendre ainsi témoignage au Christ, spécialement dans la gestion de cet ordre et dans l'accomplissement des charges séculières. » — Codex Iuris Canonici (1983), canon 225 § 2^[44]

Canon 230 § 2, above all, opens to lay people liturgical functions (lector, acolyte) long reserved to clerics or to clerics in formation, in coherence with the liturgical reform of Vatican II. For a long time, canon 230 § 1 reserved the instituted ministries of lector and acolyte to men alone; this restriction was lifted by Pope Francis by the motu proprio Spiritus Domini of 10 January 2021, which henceforth opens them to women as well.^[45]

Synodality and collegiality: canons 336-348

Book II devotes a whole part to the hierarchical structure of the Church, which did not appear as such in 1917: the pope (canons 330-335), the College of Bishops (canons 336-341) — a concept drawn directly from Lumen Gentium n. 22 —, the Synod of Bishops (canons 342-348) instituted by Paul VI in 1965, the episcopal conferences (canons 447-459).^[46][47]

Canon 336 states the juridical status of the College of Bishops:

« Le Collège des Évêques dont le chef est le Pontife Suprême et dont les Évêques sont les membres en vertu de la consécration sacramentelle et par la communion hiérarchique entre le chef et les membres du Collège, et dans lequel se perpétue le corps apostolique, est lui aussi en union avec son chef et jamais sans lui, sujet du pouvoir suprême et plénier sur l'Église tout entière. » — Codex Iuris Canonici (1983), canon 336^[48]

The expression "with its head and never without it" is crucial. It states collegiality in the Catholic sense: bishops do not form a democracy exercising over the Church a power independent of the pope, but a genuine college whose head is the successor of Peter. Canon 336 is one of the great juridical formulations of the ecclesiology of communion. It is the exact echo, in canonical language, of Lumen Gentium n. 22.^[49]

Canon 1055: a new definition of marriage

Christian marriage occupies an important place in Book IV (canons 1055-1165), with an opening definition that sums up the whole of Catholic doctrine:

« L'alliance matrimoniale, par laquelle un homme et une femme constituent entre eux une communauté de toute la vie, ordonné par son caractère naturel au bien des conjoints ainsi qu'à la génération et à l'éducation des enfants, a été élevée entre baptisés par le Christ Seigneur à la dignité de sacrement. » — Codex Iuris Canonici (1983), canon 1055 § 1^[50]

This canon condenses into one sentence the Catholic doctrine of marriage: covenant (and not mere contract), between one man and one woman (hence necessarily heterosexual), ordered to the two inseparable ends (good of the spouses and procreation), and — between the baptised — a sacrament of Christ. It is on this basis that the Code organises the whole of matrimonial law: impediments (canons 1083-1094), consent (1095-1107), canonical form (1108-1123), nullity (trials of Book VII).^[51]

Salus animarum suprema lex: canon 1752

The very last canon of the Code, canon 1752, concludes Book VII by reaffirming the ultimate end of canon law:

« Dans les causes de transfert, les dispositions du can. 1747 seront appliquées, en observant l'équité canonique et sans perdre de vue le salut des âmes qui doit toujours être dans l'Église la loi suprême. » — Codex Iuris Canonici (1983), canon 1752^[52]

The Latin expression salus animarum suprema lex — "the salvation of souls is the supreme law" — does not denote one more norm among others: it is the key for interpreting the whole Code. All the other canons, down to the most technical, are ordered to this end. It is also a safeguard against any legalistic reading of canon law: law is not the end, the soul is.^[53]

Canon 1404: Prima Sedes a nemine iudicatur

One of the very rare canons of the 1917 Code taken over verbatim into that of 1983 is the old canon 1556, which became canon 1404:

« Le Premier Siège n'est jugé par personne. » — Codex Iuris Canonici (1983), canon 1404^[54]

This principle — Prima Sedes a nemine iudicatur — states that there is no jurisdiction superior to the Roman Pontiff. The word-for-word borrowing manifests the dogmatic continuity between the two codes: the primacy of the pope, defined by Vatican I (Pastor aeternus, 1870) and confirmed by Vatican II (Lumen Gentium, n. 22), remains a fixed point.^[55][56]

The initial Book VI (1983)

Book VI of the 1983 Code (canons 1311-1399) had retained the penal architecture of the 1917 Code while lightening it. But this moderation quickly raised a problem: many canons became so vague, or so discretionary, that they discouraged the use of canonical penal law. In certain cases — notably that of sexual abuse of minors — bishops preferred to handle cases through internal administrative channels rather than prosecuting the culprits as penal procedure required.^[57][58]

Sacramentorum sanctitatis tutela (2001/2010)

To meet the urgency of abuse, John Paul II promulgated as early as 30 April 2001 the motu proprio Sacramentorum sanctitatis tutela, which reserved to the Congregation for the Doctrine of the Faith (CDF) a list of the gravest delicts (delicta graviora): abuse of minors, profanation of the Eucharist, violation of the confessional secret, and so on. The text was substantially revised by Benedict XVI on 21 May 2010, after several international scandals broke.^[59]

Among the novelties of the 2010 version: extension of prescription to twenty years (with the possibility of derogation for the CDF), inclusion of paedopornographic images (delicta graviora covering, in the 2010 version, minors under 14 — a threshold raised to under 18 by a rescript of Pope Francis in December 2019), and the possibility of an accelerated administrative trial. Benedict XVI thus took measures that would prepare the great penal reform of 2021.^[60]

Vos estis lux mundi (2019, revised in 2023)

On 9 May 2019, Pope Francis promulgated the motu proprio Vos estis lux mundi, which imposes on all priests and religious the obligation to report to their ordinary known cases of sexual abuse and negligence by their superiors. The text extends the definition of delicts to abuse of vulnerable persons (adults in situations of fragility) and organises investigations into bishops themselves, placed under the metropolitan or a bishop delegated by the Holy See.^[61]

A revision of March 2023 extended the scope of the text to lay faithful holding positions of responsibility in the Church (moderators of international associations, for example), recognising that abuses of spiritual power can occur outside the strictly clerical framework.^[62]

Pascite Gregem Dei (23 May 2021)

The great recasting of canonical penal law comes from the apostolic constitution Pascite Gregem Dei — "Tend the flock of God", an allusion to 1 Peter 5:2 — a constitution dated 23 May 2021, Pentecost day, and published on 1 June 2021. It abrogated the whole of Book VI of the Code and replaced it with a new Book VI which entered into force on 8 December 2021. It is, since 1983, the most important amendment made to the Code.^[63]

In the promulgating apostolic constitution, Francis expresses the meaning of the reform as follows:

« Dans le passé, le manque de perception du rapport intime existant dans l'Église entre l'exercice de la charité et le recours — lorsque les circonstances et la justice l'exigent — à la discipline sanctionnatrice a causé beaucoup de dommages. Cette façon de penser — l'expérience l'enseigne — risque de conduire à vivre avec des comportements contraires à la discipline des mœurs, auxquels ne suffisent pas comme remède les seules exhortations ou suggestions. […] C'est pourquoi l'application des peines devient nécessaire de la part des Pasteurs et des Supérieurs. […] En effet, la charité exige que les Pasteurs recourent au système pénal toutes les fois qu'il le faut […] » — Pape François, constitution apostolique Pascite Gregem Dei, datée du 23 mai 2021 (traduction française de l'original italien)^[64]

The idea is strong: not to punish a culprit out of false charity is to betray true charity. The new version of Book VI clarifies many delicts, lengthens prescriptions, widens the catalogue of sanctions, adds unprecedented delicts (attempted ordination of women, sexual abuse of vulnerable persons, grave economic abuse), and specifies procedures in order to make penal procedure less discretionary and more protective of both victims and the accused.^[65][66]

Canon 1 of the 1983 Code takes up, modernised, that of 1917: it expressly limits the scope of the Code to the Latin Church. The Eastern Catholic Churches of Oriental rite — Chaldeans, Maronites, Melkites, Ukrainians, Copts, Syro-Malabars, Syro-Malankaras, Ethiopians, and so on — are governed by a proper law of their own.^[67]

To fill the gap left by the Latin Code, John Paul II promulgated on 18 October 1990 the Codex Canonum Ecclesiarum Orientalium (CCEO), which entered into force on 1 October 1991. The CCEO comprises 1,546 canons structured differently from the Latin Code, because it must account for the great diversity of the Eastern traditions: those of the twenty-three Eastern Catholic Churches sui iuris — twenty-two at the time of the promulgation, joined in 2015 by the Eritrean Church erected by Francis — which form together, with the Latin Church, the twenty-four particular Churches of the Catholic communion.^[68][69][70]

The pope then presented the two codes, together with the apostolic constitution Pastor Bonus on the Roman Curia (1988) — since replaced by Praedicate Evangelium (2022) — as a single body of pontifical law:

« Le Code des canons des Églises orientales, qui paraît aujourd'hui, doit être regardé comme le complément nouveau du magistère proposé par le concile Vatican II, par lequel l'ordonnancement canonique de l'Église universelle se trouve enfin achevé, après le Code de droit canonique de l'Église latine promulgué en 1983 et la constitution apostolique sur la Curie romaine de 1988, adjointe aux deux Codes. » — Jean-Paul II, constitution apostolique Sacri Canones, 18 octobre 1990 (traduction Ignispedia du latin)^[71]

The distinction is therefore not a division: it is the normal breathing of a Catholic Church which embraces its legitimate diversity within the unity of the faith. The celebrated formula of Orientalium Ecclesiarum (Vatican II, 1964) — "Holy Mother Church […] holds in very high esteem the institutions, liturgical rites, ecclesiastical traditions and discipline of the Christian life of the Eastern Churches" — finds in the CCEO its juridical realisation.^[72]

As with the 1917 Code, serious objections have been raised against the 1983 Code. To ignore them would be disloyal; to face them squarely makes it possible to measure its true scope.

Objection — "The Code does not truly translate the ecclesiology of Vatican II"

The most elaborate objection has come from theologians and canonists who judge that the juridical translation of Lumen Gentium has remained timid: the Church as People of God is placed in Book II, but the hierarchical structure very largely reproduces that of 1917; canon 129 § 2, which seems to limit the participation of lay people in the exercise of the power of governance (potestas regiminis, still called the power of jurisdiction) to a cooperation, seems a step back from certain conciliar orientations. Other criticisms come from Catholics who would on the contrary want a more marked centralisation.^[73][74]

Answer. No Code can exhaust an ecclesiology. But that of 1983 makes, in law, a considerable leap: it opens a book on the People of God (and no longer on clerics), guarantees fundamental rights to the faithful for the first time, juridically institutes the Synod of Bishops and the episcopal conferences, and recognises the diversity of charisms. The distance between conciliar ecclesiology and its canonical expression is not a failure: it is the mark of a law which knows itself to be the servant of a life that exceeds it. And the ongoing revision (Francis's motu proprios of 2017-2024, the 2021 recasting of Book VI) shows that this translation continues.

Objection — "Penal law was weakened, hence the abuse crisis"

A frequent criticism, especially after 2010, reproaches the 1983 Code with having softened the 1917 penal law too much, which allegedly prevented bishops from energetically prosecuting sexual abuse.

Answer. The objection has a share of truth, and the Holy See itself has recognised it: that is precisely why Francis recast Book VI in 2021 by Pascite Gregem Dei, and why the motu proprios Sacramentorum sanctitatis tutela (2001/2010) and Vos estis lux mundi (2019/2023) restored a robust penal framework. But the principal flaw of the first version of Book VI was not so much juridical as cultural: too many pastors wrongly judged that acting with mercy meant not sanctioning, or that public scandal must be avoided. The 2021 reform corrects both sides: the letter of the law, and the pastoral attitude. Far from being a failure of codification, this correction confirms that the 1983 Code is a living law, capable of reforming itself without denying its foundations.

Objection — "Canon 1055 on marriage is too restrictive"

Some challenge the definition of marriage in canon 1055 — a heterosexual, indissoluble covenant ordered to the good of the spouses and to procreation — asking the Church to open up to other unions, or to relax indissolubility.

Answer. Canon 1055 merely reformulates in canonical language the Catholic doctrine of marriage, founded on Matthew 19:6 ("What God has joined together, let man not separate") and confirmed by every council since Trent. It therefore does not depend on the authority of the Code, but on revelation. Sacrae Disciplinae Leges is explicit: the Code's mission is not to modify doctrine, but to organise its juridical expression. To wish to reform canon 1055 without touching the dogma of marriage would be to misunderstand what a code is.^[75][76]

The 1983 Code is neither an oppressive apparatus nor an obsolete framework. It is, in practice, the book a bishop must open when taking possession of a diocese, a parish priest celebrating a marriage, a religious pronouncing vows, an ecclesiastical judge instructing a case, or a faithful who considers himself harmed by an administrative decision and wishes to have recourse. It is also the book a theologian must cite who wishes to articulate doctrine and discipline.

For the non-specialist Catholic reader, the Code remains accessible if three keys for reading it are accepted.

First, to read with Vatican II. The Code is fully intelligible only in the light of the conciliar constitutions, above all Lumen Gentium and Sacrosanctum Concilium. To read canon 204 without Lumen Gentium n. 31 is to read a sign without knowing the thing signified.

Next, to read as a grammar, not as a set of regulations. The Code gives the vocabulary, syntax and conjugations of ecclesial law; it does not exhaust ecclesial life, just as a grammar does not exhaust literature. Canon 1752 — salus animarum suprema lex — explicitly invites the reader always to refer the letter of the law to the real good of souls.

Finally, to read with confidence. The Code is the work of nearly twenty years of collegial labour involving thousands of bishops, canonists, religious and lay people, under the direct authority of Saint John Paul II. It is not an administrative trick, but a solemn act of government of the Church.

The 1983 Code of Canon Law, heir to the Pio-Benedictine Code and servant of conciliar ecclesiology, remains for forty years more — and perhaps far longer — the juridical charter of the Latin Catholic communion, peacefully awaiting a new revision which no pope has yet announced.

• The 1917 Code of Canon Law — the Pio-Benedictine Code of which the 1983 Code is the direct heir.
• The Second Vatican Council (1962-1965) — the council whose ecclesiology permeates the whole of the 1983 Code.
• The First Vatican Council (1869-1870) — the council where the primacy of the pope was defined, taken up in canon 1404.
• The Council of Trent (1545-1563) — the great disciplinary reform which still marks modern canon law.
• The Dicastery for the Doctrine of the Faith — the Roman authority of reference for delicta graviora.
• The Nihil Obstat and the Imprimatur — canonical institutions for the oversight of publications.
