"If any man thirst, let him come and drink from the rivers of living water" (cf. John 7:38). Where shall he who thirsts come? To heretics where the fountain and river of water is in no way life-giving? Or to the Church, which is One?

And according as we say, "Our Father," because He is The Father of those who understand and believe; so also we call it "our Bread," because Christ is The Bread of those who are in union with His Body. And we ask that this Bread should be given to us daily, that we who are in Christ, and daily receive The Eucharist for the Food of Salvation, may not by the interposition of some heinous sin...be separated from Christ's Body.

Whatever a man prefers to God, that he makes a god to himself.

Knowing that there is one Baptism, we who hold the head and root of the One Church know for certain that to him who is outside the Church nothing is lawful.

Persevere in labors that lead to salvation. Always be busy in spiritual actions. In this way, no matter how often the enemy of our souls approaches, no matter how many times he may try to come near us, he'll find our hearts closed and armed against him.

Peter, in showing that the Church is one and that only those who are in the Church can be saved, said: "In the Ark of Noah certain persons, numbering only eight, were saved by water, which Baptism effects in like manner for you" (1 Peter 3:20). He proves and demonstrates that the solitary Ark of Noah was the figure of the One Church. If, at the time of this Baptism of the world anyone could have been saved without having been in the Ark of Noah, then he who is outside the Church could now be brought to life by Baptism.

This supernatural bread and this consecrated chalice are for the health and salvation of mankind.
