Great are those two gifts, wisdom and continence: wisdom, forsooth, whereby we are formed in the knowledge of God; continence whereby we are not conformed to this world.
Saint AugustineThe 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 Augustine
