True peace consists in not separating ourselves from the will of God.

There is but one Church in which men find salvation, just as outside the ark of Noah it was not possible for anyone to be saved.

Pain itself can be pleasurable accidentally in so far as it is accompanied by wonder, as in stage-plays; or in so far as it recalls a beloved object to one's memory, and makes one feel one's love for the thing, whose absence gives us pain. Consequently, since love is pleasant, both pain and whatever else results from love, in so far as they remind us of our love, are pleasant.

The celebration of Holy Mass is as valuable as the death of Jesus on the cross.

Better to illuminate than merely to shine.
