Apostolic Constitutions, Book II 33

1For if the divine oracle says, concerning our parents according to the flesh, Honour your father and your mother, that it may be well with you; and, He that curses his father or his mother, let him die the death; how much more should the word exhort you to honour your spiritual parents, and to love them as your benefactors and ambassadors with God, who have regenerated you by water, and endued you with the fullness of the Holy Spirit, who have fed you with the word as with milk, who have nourished you with doctrine, who have confirmed you by their admonitions, who have imparted to you the saving body and precious blood of Christ, who have loosed you from your sins, who have made you partakers of the holy and sacred eucharist, who have admitted you to be partakers and fellow-heirs of the promise of God! Reverence these, and honour them with all kinds of honour; for they have obtained from God the power of life and death, in their judging of sinners, and condemning them to the death of eternal fire, as also of loosing returning sinners from their sins, and of restoring them to a new life.
