Council of Trent: Session XIII, Eucharist, Chapter II

CHAPTER II. On the reason of the Institution of this most holy Sacrament.

Wherefore, our Saviour, when about to depart out of this world to the Father, instituted this Sacrament, in which He poured forth as it were the riches of His divine love towards man, making a remembrance of his wonderful works; and He commanded us, in the participation thereof, to venerate His memory, and to show forth his death until He come to judge the world. And He would also that this sacrement should be received as the spiritual food of souls, whereby may be fed and strengthened those who live with His life who said, He that eateth me, the same also shall live by me; and as an antidote, whereby we may be freed from daily faults, and be preserved from mortal sins. He would, furthermore, have it be a pledge of our glory to come, and everlasting happiness, and thus be a symbol of that one body whereof He is the head, and to which He would fain have us as members be united by the closest bond of faith, hope, and charity, that we might all speak the same things, and there might be no schisms amongst us.
