“These explanatory notes and comments on the discipline of the Code of Canon Law concerning the sacrament of orders are divided into six unequal parts: [1] the introductory and doctrinal canons; [2] the celebration and the minister of ordination; [3] the candidate for ordination; [4] irregularities and other impediments; [5] the cessation of the impediments; and [6] the required documents and investigations relative to and the registration of ordination. [...] The treatment is strictly canonical, not liturgical, and only minimally theological. The purpose of these notes is to explain the meaning of the law as it stands, not what the law should be.”
