The Canons of the Council in Trullo; Often Called The Quinisext Council 30Canon XXX.

Willing to do all things for the edification of the Church, we have determined to take care even of priests who are in barbarian churches. Wherefore if they think that they ought to exceed the Apostolic Canon concerning the not putting away of a wife on the pretext of piety and religion, and to do beyond that which is commanded, and therefore abstain by agreement with their wives from cohabitation, we decree they ought no longer to live with them in any way, so that hereby they may afford us a perfect demonstration of their promise. But we have conceded this to them on no other ground than their narrowness, and foreign and unsettled manners.
