Canon 25
We add, most dear brethren, moreover, since we have heard of the incontinency of certain clerics, even if they were only lectors, towards their wives, it pleased us what had been stated in various councils:
The subdeacons who touch the holy mysteries, the deacons, presbyters, but also bishops, in accordance with former statutes, should abstain from their wives, so that they can be seen as though they had them not. If they do not do it, they should be removed from office. But the rest of the clergy are not to be compelled to this, unless more mature in age.
And the whole council said: What your holiness has justly said is holy, and pleasing to God, and we confirm it.
