Catena Aurea by Aquinas
(ubi sup.) As therefore He had said, For who so ever will save his life shall lose it, lest any one should suppose this loss to be equivalent to that salvation, He adds, For what shall it profit a man, if he shall gain the whole world, and lose his own soul, &c. As if He said, Think not that he has saved his soul, who has shunned the perils of the cross; for when a man, at the cost of his soul, that is, his life, gains the whole world, what has he besides, now that his soul is perishing? Has he another soul to give for his soul? For a man can give the price of his house in exchange for the house, but in losing his soul, he has not another soul to give. And it is with a purpose that He says, Or what shall a man give in exchange for his soul? for God, in exchange for our salvation, has given the precious blood of Jesus Christ.
