Let not a bishop, a priest, or a deacon cast off his own wife under pretence of piety; but if he does cast her off, let him be suspended. If he go on in it, let him be deprived. (Canon 6)
Council of Gangra ca. 4th cent.
If any one shall maintain, concerning a married presbyter, that is not lawful to partake of the oblation when he offers it, let him be anathema. (Canon 4)
Council of Carthage ca. 419
Faustinus, the bishop of the Potentine Church, in the province of Picenum, a legate of the Roman Church, said: It seems good that a bishop, a presbyter, and a deacon, or whoever perform the sacraments, should be keepers of modesty and should abstain from their wives.
By all the bishops it was said: It is right that all who serve the altar should keep pudicity from all women. (Canon 4)
Aurelius, the bishop, said: We add, most dear brethren, moreover, since we have heard of the incontinency of certain clerics, even of readers, towards their wives, it seemed good that what had been enacted in various councils should be confirmed, to wit, that subdeacons who wait upon the holy mysteries, and deacons, and presbyters, as well as bishops according to former statutes, should contain from their wives, so that they should be as though they had them not and unless they so act, let them be removed from office. But the rest of the clergy are not to be compelled to this, unless they be of mature age. And by the whole council it was said: What your holiness has said is just, holy, and pleasing to God, and we confirm it. (Canon 25)
Council in Trullo ca. 692
Moreover this also has come to our knowledge, that in Africa and Libya and in other places the most God-beloved bishops in those parts do not refuse to live with their wives, even after consecration, thereby giving scandal and offense to the people. Since, therefore, it is our particular care that all things tend to the good of the flock placed in our hands and committed to us—it has seemed good that henceforth nothing of the kind shall in any way occur. And we say this, not to abolish and overthrow what things were established of old by Apostolic authority, but as caring for the health of the people and their advance to better things, and lest the ecclesiastical state should suffer any reproach. For the divine Apostle says:
Do all to the glory of God, give none offense, neither to the Jews, nor to the Greeks, nor to the Church of God, even as I please all men in all things, not seeking my own profit but the profit of many, that they may be saved. Be imitators of me even as I also am of Christ. But if any shall have been observed to do such a thing, let him be deposed. (Canon 12)
Since we know it to be handed down as a rule of the Roman Church that those who are deemed worthy to be advanced to the diaconate or presbyterate should promise no longer to cohabit with their wives, we, preserving the ancient rule and apostolic perfection and order, will that the lawful marriages of men who are in holy orders be from this time forward firm, by no means dissolving their union with their wives nor depriving them of their mutual intercourse at a convenient time. Wherefore, if anyone shall have been found worthy to be ordained subdeacon, or deacon, or presbyter, he is by no means to be prohibited from admittance to such a rank, even if he shall live with a lawful wife. Nor shall it be demanded of him at the time of his ordination that he promise to abstain from lawful intercourse with his wife: lest we should affect injuriously marriage constituted by God and blessed by his presence, as the Gospel says:
What God has joined together let no man put asunder; and the Apostle says,
Marriage is honourable and the bed undefiled; and again,
Are you bound to a wife? Seek not to be loosed. But we know, as they who assembled at Carthage (with a care for the honest life of the clergy) said, that subdeacons, who handle the Holy Mysteries, and deacons, and presbyters should abstain from their consorts according to their own course [of ministration]. So that what has been handed down through the Apostles and preserved by ancient custom, we too likewise maintain, knowing that there is a time for all things and especially for fasting and prayer. For it is meet that they who assist at the divine altar should be absolutely continent when they are handling holy things, in order that they may be able to obtain from God what they ask in sincerity.
If therefore anyone shall have dared, contrary to the Apostolic Canons, to deprive any of those who are in holy orders, presbyter, or deacon, or subdeacon of cohabitation and intercourse with his lawful wife, let him be deposed. In like manner also if any presbyter or deacon on pretence of piety has dismissed his wife, let him be excluded from communion; and if he persevere in this let him be deposed. (Canon 13)
The wife of him who is advanced to the Episcopal dignity, shall be separated from her husband by their mutual consent, and after his ordination and consecration to the episcopate she shall enter a monastery situated at a distance from the abode of the bishop, and there let her enjoy the bishop’s provision. And if she is deemed worthy she may be advanced to the dignity of a deaconess. (Canon 48)
