It must be understood that prime matter, and form as well, is neither generated nor corrupted, because every generation is from something to something. Now that from which generation proceeds is matter, and that to which it proceeds is form. So that, if matter or form were generated, there would be a matter for matter and a form for form, endlessly. Whence, there is generation only of the composite, properly speaking.
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 to regard the fact that God cannot do the impossible as a limitation on his powers.
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
