Council of Trent: Session VII, On Baptism, Canon XIV

ON BAPTISM

CANON XIV.-If any one saith, that those who have been thus baptized when children, are, when they have grown up, to be asked whether they will ratify what their sponsors promised in their names when they were baptized; and that, in case they answer that they will not, they are to be left to their own will; and are not to be compelled meanwhile to a Christian life by any other penalty, save that they be excluded from the participation of the Eucharist, and of the other sacraments, until they repent; let him be anathema.
