CANON 6
Summary. Clerics living with women shall be deprived of their office and benefice.
Text. We also decree that those who in the subdiaconate and higher orders have contracted marriage or have concubines, be deprived of their office and ecclesiastical benefice. For since they should be and be called the temple of God, the vessel of the Lord, the abode of the Holy Spirit, it is unbecoming that they indulge in marriage and in impurities. [[17]]
Note 17. Identical with canon 4 of Clermont and Reims. Cf. canon 21 of I Lateran.
CANON 7
Summary. Masses celebrated by members of the clergy who have wives or concubines are not to be attended by anyone.
Text. Following in the footsteps of our predecessors, the Roman pontiff s Gregory VII, Urban, and Paschal, we command that no one attend the masses of those who are known to have wives or concubines. But that the law of continence and purity, so pleasing to God, may become more general among persons constituted in sacred orders, we decree that bishops, priests, deacons, subdeacons, canons regular, monks, and professed clerics (conversi) who, transgressing the holy precept, have dared to contract marriage, shall be separated. For a union of this kind which has been contracted in violation of the ecclesiastical law, we do not regard as matrimony. Those who have been separated from each other, shall do penance commensurate with such excesses.
CANON 8
Summary. This applies also to nuns.
Text. We decree that the same be observed with regard to nuns if, which God forbid, they attempt to marry.
CANON 17
Summary. Marriages between blood-relatives are prohibited.
Text. We absolutely forbid marriages between blood-relatives. The declarations of the holy fathers and of the holy Church of God condemn incest of this kind, which, encouraged by the enemy of the human race, has become so widespread. Even the civil laws brand with infamy and dispossess of all hereditary rights those born of such unions.[[28]]
Note 28. Cf. canon 5 of I Lateran.
CANON 23
Summary. Those who reject the sacraments are condemned, and the civil power is invoked to restrain their mischief.
Text. Those who, simulating a species of religious zeal, reject the sacrament of the body and blood of the Lord, the baptism of infants, the priesthood, and other ecclesiastical orders, as well as matrimony, we condemn and cast out of the Church as heretics, and ordain that they be restrained by the civil power. For their partisans also we decree the same penalty.[[36]]
Comment. This canon is a word for word repetition of canon 3 of the Synod of Toulouse (1119) [[37]] and was directed against the Petrobrusians, a heretical sect of the twelfth century, so named after their founder, the renegade priest Peter of Bruys, whom Peter the Venerable and Abelard characterized as one of the most dangerous of heretics. Their principal doctrinal tenets were five: (i) Baptism must be preceded by personal faith; hence its administration to children who have not yet attained the use of reason is worthless. (2) Christians need no holy place in which to pray. Their prayers, if worthy, are heard in a barn as well as in a church; hence churches must not be built, and those already built must be destroyed. This doctrine harmonizes with the teachings of the spiritualistic sects of the preceding century. (3) Crosses must be destroyed; because this instrument on which Christ suffered so much, must not be an object of veneration, but of detestation. (4) What is offered daily in the mass is pure nothing. Christ gave His flesh and blood to His disciples once and it cannot be given again. (5) Prayers and good works by the living cannot profit the dead, and God ridicules all ceremonies and chant. The reference in the canon to the rejection of matrimony does not seem to a apply to the Petrobrusians. Probably the council had other sects in mind.
