He says that it is like, because these two commandments are harmonious one with the other, and mutually contain the other. For he who loves God, loves also His creature; but the chief of His creatures is man, wherefore he who loves God ought to love all men. But he who loves his neighbor, who so often offends him, ought much more to love Him, who is ever giving him benefits. And therefore on account of the connection between these commandments, He adds, “There is none other commandment greater than these.”
It goes on: “And the Scribe said unto Him, Well, Master, thou hast said the truth: for there is one God, and there is none other but He: and to love Him with all the heart, and with all the soul, and with all the understanding, and with all the strength, and to love his neighbour as himself, is more than all whole burnt offerings and sacrifices.”
