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.
Thomas AquinasWe are like children, who stand in need of masters to enlighten us and direct us; God has provided for this, by appointing his angels to be our teachers and guides.
Thomas AquinasIt is a sin directly against one's neighbour, since one man cannot over-abound in external riches, without another man lacking them.
Thomas AquinasAs mariners are guided into port by the shining of a star, so Christians are guided to heaven by Mary.
Thomas AquinasIt seems that God does not exist; because if one of two contraries be infinite, the other would be altogether destroyed. But the word "God" means that He is infinite goodness. If, therefore, God existed, there would be no evil discoverable; but there is evil in the world. Therefore God does not exist.
Thomas Aquinas
