Canon 30 Priests in barbarian churches who separate from wives

Wishing to do all things for the edification of the Church, we have determined to exercise oikonomia towards the priests in the barbarian churches as well; so that, if they think they ought to go beyond the apostolic canon, the one concerning not casting out one's own wife on the pretext of piety, and to do more than what has been defined, and on this account, by agreement with their own consorts, abstain from intercourse with one another, we decree that these no longer live with them in any manner whatever, so that thereby they may furnish us with complete proof of their promise. And we have conceded this to them for no other reason than on account of the littleness of their mind and the alien and unsettled character of their ways.
