As the object known is in the knower, to the extent that it is known, so the beloved must be in the lover, as loved. The, lover is, in some way, moved by the beloved with a certain interior impulse. Therefore, since a mover is in contact with the object moved, the beloved must be intrinsic to the lover. But God, just as He understands Himself, must likewise love Himself; for good, as apprehended, is in itself lovable. Consequently God is in Himself as beloved in lover.
