Canon 32
On the adoptive women introduced in secret (subintroductae).
No bishop, presbyter, or deacon, and absolutely no one from the clergy shall have a right to introduce to his house a woman accepting her in place of daughter, sister, or mother, unless it is really his true sister-german, or sister of mother or father, or any other person free of any wrong suspicion. Similarly, we forbid religious women to be in familiar relations with unrelated laymen and with those who are not bound by the fear of God nor keep the discipline of continence.
