Seven books, 1752 canons

The Code contains 1752 canons arranged in seven books:

  • Book I: General Norms
  • Book II: The People of God
  • Book III: The Teaching Function of the Church
  • Book IV: The Sanctifying Function of the Church
  • Book V: The Temporal Goods of the Church
  • Book VI: Penal Sanctions in the Church
  • Book VII: Processes

A canon is cited by number, for example “c. 1055 §1.” Many canons are divided into paragraphs (§) and numbered items.

Marriage as a covenant

The matrimonial covenant, by which a man and a woman establish between themselves a partnership of the whole of life and which is ordered by its nature to the good of the spouses and the procreation and education of offspring, has been raised by Christ the Lord to the dignity of a sacrament between the baptized.

Paragraph 2 adds: “For this reason, a valid matrimonial contract cannot exist between the baptized without it being by that fact a sacrament.” Most cases in church tribunals concern whether a marriage was valid.

The final canon

In cases of transfer the prescripts of can. 1747 are to be applied, canonical equity is to be observed, and the salvation of souls, which must always be the supreme law in the Church, is to be kept before one’s eyes.

The canon deals with transferring a pastor. Its closing words, the salvation of souls as “the supreme law in the Church,” are often quoted as the purpose of the whole Code.
