The soul, which is the first principle of life, is not a body, but the act of a body; just as heat, which is the principle of calefaction, is not a body, but an act of a body.
Thomas Aquinas
-
It is necessary to posit something which is necessary of itself, and has no cause of its necessity outside of itself but is the cause of necessity in other things. And all people call this thing God.
Thomas Aquinas
-
Gods are called many by the error of some who worshipped many deities, thinking as they did the planets and other stars were gods, and also the separate parts of the world.

Thomas Aquinas
-
Without doubt one is allowed to resist against the unjust aggressor to one's life, one's goods or one's physical integrity; sometimes, even 'til the aggressor's death... In fact, this act is aimed at preserving one's life or one's goods and to make the aggressor powerless. Thus, it is a good act, which is the right of the victim.
Thomas Aquinas
-
Just as in a physical body the operation of one member contributes to the good of the whole body, so it is in a spiritual body such as the Church. And since all the faithful are one body, the good of one member is communicated to another; everyone members, as the Apostle says, of one another. For that reason, among the points of faith handed down by the Apostles, is that there is a community of goods in the Church, and this is expressed in the words Communion of Saints.
Thomas Aquinas
-
It 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
-
The servants of God...whether provoked by word or work, by keeping themselves tranquil and peaceful, evince a perfect nobleness of soul.

We ought to cherish the body. Our body's substance is not from an evil principle, as the Manicheans imagine, but from God. And therefore, we ought to cherish the body by the friendship of love, by which we love God.
Thomas Aquinas
-
I answer that, Even, as in the blessed in heaven there will be most perfect charity, so in the damned there will be the most perfect hate.
Thomas Aquinas
-
Of all the pursuits open to men, the search for wisdom is most perfect, more sublime, more profitable, and more full of joy.
Thomas Aquinas
-
Do not wish to jump immediately from the streams to the sea, because one has to go through easier things to the more difficult.
Thomas Aquinas
