Since faith rests upon infallible truth, and since the contrary of a truth can never be demonstrated, it is clear that the arguments brought against faith cannot be demonstrations, but are difficulties that can be answered.
Thomas AquinasTo restore man, who had been laid low by sin, to the heights of divine glory, the Word of the eternal Father, though containing all things within His immensity, willed to become small. This He did not by putting aside His greatness but by taking to Himself our littleness.
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 AquinasLikewise grace and glory are referred to the same genus, since grace is nothing other than a certain first beginning of glory in us.
Thomas AquinasIt 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.
