From the Council of Auvergne, A.D. 535

Canon VI. If anyone is joined in conjugal association to Jewish depravity and is mingled in carnal consortship, whether a Christian woman with a Jew or a Jew with a Christian woman, whosoever of these is recognized to have admitted so great an impiety, let him be segregated from the assembly of Christians, without banquet and communion of the Church, to whose enemies he is associated.

Cf. Canon XIX of the preceding Council of Orleans. But the canon just cited perhaps looks to another second Synod of Auvergne, A.D. 549.

Canon XII. If anyone has believed that the widow of his brother, the sister of his wife, his stepdaughter, his female cousin or cousin's daughter, or the widow of his paternal or maternal uncle, is to be violated by the consortship of carnal contagion, and with sacrilegious daring has broken through the authority of the divine law and the rights of nature, and to her to whom he ought to have shown the consolations of charity and pious affection, has attempted to bring force, as an enemy of his own and an assailant of chastity, let him be struck by the sentence of the apostolic constitution. And so long as he is engaged in so great a crime, let him be deprived of the Christian assembly and banquet, and at the same time of the communion of Mother Church.

Cf. Canon LXI of the Council of Agde, above. Here also it is evident that nuptials of this sort were held as null, since they are judged a breaking of the authority of the divine law and of natural right, a sacrilegious daring, a violation of relatives, an assault upon chastity. Moreover, those who are joined in this way are prohibited from coming together perpetually, under penalty of excommunication.

Canon XIII. When presbyters and deacons are advanced to the summit of the sublime dignity, let them renounce entirely the acts of the world, and, chosen for the sacred ministry, let them repudiate carnal consortship, and exchange the cohabitation of the former mingling for the affection of brotherhood; and whoever is a presbyter or deacon, once the blessing has been received by divine gift, is at once made the brother of his wife, from a spouse.

Here presbyters and deacons assumed from among the married are treated more mildly than in Canon XXXVII of the Council of Epaon and Canon XVI of the Council of Agde, above.
