The bread that you see on the altar is the Body of Christ as soon as it is sanctified by God's word. The chalice, or better what is contained in the chalice, is the Blood of Christ as soon as it is sanctified by God's word
Saint AugustineThere is nothing more serious than the sacrilege of schism because there is no just cause for severing the unity of the Church.
Saint AugustineLove all men, even your enemies; love them, not because they are your brothers, but that they may become your brothers. Thus you will ever burn with fraternal love, both for him who is already your brother and for your enemy, that he may by loving become your brother.
Saint Augustine
