““—Baptism is administered by means of washing, i. e. applying the water to the subject. This application must be a true ablu tion (ablutio vera), i. e. it must involve a contact that is both physical and successive. In other words, the baptismal water must actually touch the body and flow over it. This twofold contact can be effected by immersion, effusion, and aspersion. The validity of the present practice of effusion has been indirectly defined against the schismatic Greeks by the Council of Trent: " If any one saith that in the Roman Church, which is the mother and mistress of all churches, there is not the true doctrine concerning the Sacrament of Baptism, let him be anathema.””
