§2. Through instruction and the first experience of Christian life, catechumens are to be initiated suitably into the mystery of salvation and introduced into the life of the faith, the liturgy, the charity of the people of God, and the apostolate.
§3. It is for the conference of bishops to issue statutes which regulate the catechumenate by determining what things must be expected of the catechumens and by defining what prerogatives are to be recognized as theirs.
