Council of Verona, 1184

[From the decree "Ad abolendum" against the heretics]

All who, regarding the sacrament of the Body and Blood of our Lord Jesus Christ, or regarding baptism or the confession of sins, matrimony or the other ecclesiastical sacraments, do not fear to think or to teach otherwise than the most holy Roman Church teaches and observes; and in general, whomsoever the same Roman Church or individual bishops through their dioceses with the advice of the clergy or the clergy themselves, if the episcopal see is vacant, with the advice if it is necessary of neighboring bishops, shall judge as heretics, we bind with a like bond of perpetual anathema.
