Quotes from St. Thomas Aquinas

I answer that, Each man has an angel guardian appointed to him. This rests upon the fact that the guardianship of angels belongs to the execution of Divine providence concerning men.

No man ought to despise or in any way injure another man without urgent cause: and, consequently, unless we have evident indications of a person's wickedness, we ought to deem him good, by interpreting for the best whatever is doubtful about him.

He who interprets doubtful matters for the best, may happen to be deceived more often than not; yet it is better to err frequently through thinking well of a wicked man, than to err less frequently through having an evil opinion of a good man, because in the latter case an injury is inflicted, but not in the former.

If, however, we understand by the firmament that part of the air in which the clouds are collected, then the waters above the firmament must rather be the vapors resolved from the waters which are raised above a part of the atmosphere, and from which the rain falls.

But to say, as some writers alluded to by Augustine (Gen. ad lit. ii, 4), that waters resolved into vapor may be lifted above the starry heaven, is a mere absurdity.

Happiness itself, being a perfection of the soul, is a good inherent in the soul: but that in which happiness consists, or the object that makes one happy, is something outside the soul.

In Hebrew, His name is Jesus, in Greek, Soter, in Latin, Salvator; but men say Christus in Greek, Messias in Hebrew, Unctus in Latin, that is, King and Priest.

I answer that, God alone, Father, Son and Holy Ghost, is from eternity. Catholic Faith holds this without doubt; and everything to the contrary must be rejected as heretical. For God so produced creatures that He made them "from nothing"; that is, after they had not been.

But the perfection of divine goodness is found in one simple thing

The act that anything evil puts forth is due to the strength of goodness, but a deficient goodness. For if there were nothing of good there, neither would there be any being, nor any action: again, if the goodness were not deficient, neither would there be any evil.

I answer that, The truth of this question is quite clear if we consider the divine simplicity. For it was shown above (Q[3], A[3]) that the divine simplicity requires that in God essence is the same as "suppositum," which in intellectual substances is nothing else than person. But a difficulty seems to arise from the fact that while the divine persons are multiplied, the essence nevertheless retains its unity.

No more does one who is on a journey have to think at every step of his destination.
