That clerics or those who are continent shall not visit virgins or widows.

Neither clerics nor those who profess continence should enter the houses of widows or virgins without the bidding or consent of the bishops or presbyters: and then let them not go alone, but with some other of the clergy, or with those assigned by the bishop or presbyter for this purpose; not even bishops and presbyters shall go alone to women of this sort, except some of the clergy are present or some other grave Christian men.
