It is He who gave to this intellectual nature free-will of such a kind, that if he wishes to forsake God his blessedness, misery should forthwith result.
Everyone who observes himself doubting observes a truth, and about that which he observes he is certain; therefore he is certain about a truth. Everyone therefore who doubts whether truth exists has in himself a truth on which not to doubt.... Hence one who can doubt at all ought not to doubt the existence of truth.
Baptism does not profit a man outside unity with the Church ... For many heretics also possess this Sacrament but not the fruits of salvation ... The benefits which flow from Baptism are necessarily fruits which belong to the true Church alone. Children Baptized in other communions cease to be members of the Church when, after reaching the age of reason, they make formal profession of heresy, as, for example, by receiving communion in a non-Catholic Church.
To seek the greatest good is to live well, and to live well is nothing other than to love God with the whole heart, the whole soul, and the whole mind: It is therefore obvious that this love must be kept whole and uncorrupt, that is temperance; it should not be overcome with difficulties, that is fortitude, it must not be subservient to anything else, that is justice; it must discriminate among things so as not to be deceived by falsity or fraud, that is prudence.
Though there are very many nations all over the earth, ...there are no more than two kinds of human society, which we may justly call two cities, ...one consisting of those who live according to man, the other of those who live according to God ....To the City of Man belong the enemies of God, ...so inflamed with hatred against the City of God.
Quid est ergo tempus? Si nemo ex me quaerat, scio; si quaerenti explicare velim, nescio. What, then, is time? I know well enough what it is, provided that nobodyasksme; but if Iamasked what it is and try to explain, I am baffled.
Men go forth to wonder at the height of mountains, the huge waves of the sea, the broad flow of the ocean, the course of the stars-and forget to wonder at themselves. Beware of despairing about yourself: you are commanded to put your trust in God, and not in yourself.
Whoever seems to himself to have understood the Scriptures in such a way that he does not build up that double love of God and neighbor has not yet understood.
I held my heart back from positively accepting anything, since I was afraid of another fall, and in this condition of suspense I was being all the more killed.
