This brief canon raises several questions:
1. Common sense suggests that clerics were forbidden to live with unrelated ("extraneous") women, and nuns with unrelated men, but is it really true, or may the prohibition extend to a general ban on unrelated people living with clerics and nuns?
2. What exactly does an "unrelated" person mean? Does it extend to other family members, household slaves and so on?
3. What is the relation of the canon to the clerical celibate? I think that it refers to presbyters who were either unmarried or left their wives after ordination, because a wife probably would be much more intolerant than the council canon against an "unrelated woman" in her husband's house.
4. We translate "sanctimoniales feminae" as "nuns", for the lack of better words. It is not exactly clear whether they are the laity threatened with excommunication in the second part of the canon; this is probable, althought the word may refer also to the "unrelated" men living with them, and "unrelated" women living with the clerics.
