Pray thee, spare, thyself at times: for it becomes a wise man sometimes to relax the high pressure of his attention to work.

Just as a man cannot live in the flesh unless he is born in the flesh, even so a man cannot have the spiritual life of grace unless he is born again spiritually. This regeneration is effected by Baptism: "Unless a man is born again of water and the Holy Spirit, he cannot enter into the kingdom of God" (Jn 3:5)

All men are equal in nature, and also in original sin. It is in the merits and demerits of their actions that they differ.

Man is closer to God according to his existence in grace than he is according to his existence in nature.

An angel can illumine the thought and mind of man by strengthening the power of vision and by bringing within his reach some truth which the angel himself contemplates.

The happy man in this life needs friends.

A person is disposed to an act of choice by an angel ... in two ways. Sometimes, a man's understanding is enlightened by an angel to know what is good, but it is not instructed as to the reason why ... But sometimes he is instructed by angelic illumination, both that this act is good and as to the reason why it is good.

It is only God who creates. Man merely rearranges.

Future contingents cannot be certain to us, because we know them as such. They can be certain only to God whose understanding is in eternity above time. Just as a man going along a road does not see those who come after him; but the man who sees the whole road from a height sees all those who are going along the road at the same time.
