OF THE PERFECTION OF DIVINE LOVE WHICH EXISTS IN GOD ALONE
IN each of the two divisions of charity there are many degrees. As regards the love of God, the first and supreme degree of perfection of Divine love belongs to God alone. This is the case on account both of the One who is loved, and of the one who loves. It is the case on account of the loved one, because every object is loved in proportion to the qualities which make it lovable. It is the case on account of the lover, because an object is loved in proportion to the whole capacity of the one who loves. Now, as every object is lovable in proportion to its goodness, the goodness of God, which is infinite, must be infinitely lovable. But no creature can love infinitely, because no finite power is able to elicit an infinite act. Therefore, God alone, whose power of loving equals His Goodness, can love Himself perfectly in the first degree of perfection.
