document — Palmieri, On Christian Marriage
From the Second Lateran Council, Ecumenical, A.D. 1139
Canon VII. We establish that bishops, priests, deacons, subdeacons, regular canons, monks, and professed conversi, who, transgressing their holy purpose, have presumed to unite wives to themselves, be separated. For we judge that a coupling of this sort, which is known to have been contracted against the ecclesiastical rule, is not marriage. Let those also, separated from one another, perform worthy penance for such great excesses.
Canon VIII. We decree that the same also be observed concerning religious women, if, which may it not be, they have attempted to marry.
Cf. Canon XXI of the First Lateran Council. The same two aforesaid canons were renewed in the Council of Rheims, A.D. 1148, by Eugene III, Canon XVII.
Canon XVII. We entirely prohibit conjunctions of blood-relatives from being made. For this kind of incest, which now, almost by the goad of the enemy of the human race, has been turned into usage, the statutes of the holy Fathers and the most holy Church of God detest. The laws also of the age pronounce those born from such cohabitation infamous and repel them from inheritance.
Cf. the preceding canon of the Lateran Synod. The same canon had been established in the Council of Clermont, A.D. 1130, and in that of Rheims by the same Innocent, perhaps also in the Council of Auvergne, which the same Pontiff held in the preceding year.
Moreover the authority of secular laws, both here and in the First Lateran Council, is brought forward for persuasion, not as a source of law, which depends on the statutes of the Fathers and of the Church.
Canon XXIII. Those, moreover, who, simulating an appearance of religiosity, condemn the sacrament of the Body and Blood of the Lord, the baptism of children, the priesthood and the other ecclesiastical orders, and the legitimate bonds of nuptials, we expel and condemn as heretics from the Church of God, and we command that they be restrained by external powers.
Cf. Canon III of the Council of Toulouse under Callistus II.
