The Lord s Supper is the unity of the Body of Christ, not only in the Sacrament of the Altar, but in the bond of peace.
St. Augustine: In Joan. Evang. 27, 11.
When sacrifices either of the altar or of alms of any kind are offered for all the baptized dead, they are thank offerings for the good; for those who were not very bad they are propitiatory offerings; and, though for the very bad they have no significance as helps for the dead, they do bring a measure of consolation to the living. And those who actually receive such profit, receive it in the form either of a complete remission of sin, or of at least an amelioration of their sentence.
St. Augustine: Enchiridion, 110.
