On these two commandments hang all the law and the prophets.

Theophylact of Ochrid
AD 1107
Out of immeasurable spite this man comes forward to put the Lord to the test. For when they saw the Sadducees put to shame and the Lord praised for His wisdom, they came forward to test Him to see if He would add something to the first commandment, and thus give them the chance to accuse Him of being an innovator who corrects the law. But the Lord discloses their malice, and because they came not to learn, but rather, devoid of love, to show their envy and their spite, He reveals to them the exceedingly great love expressed by the commandments. And He teaches that we ought not to love God partially, but to give all of ourselves to God. For we perceive these three distinctions of the human soul: the vegetative, the animal, and the rational. When the soul grows and is nourished and begets what is like unto it, it resembles the plants; when it experiences anger or desire, it is like the animals; when it understands, it is called rational. See, then, how these three facets are indicated here. "Thou shalt love thy God with all thy heart" — this is the animal part of a man; "and with all thy soul [or life]" — this is the vegetative part of a man, for plants are alive and animate; "and with all thy mind" — this is the rational (Deut. 6:5). So one must love God with all one’s soul, that is, one must attend to Him with all the parts and powers of one’s soul. "This is the first and great commandment," training us in piety. "The second is like unto it," which exhorts us to do to other men what is just and right. For there are two things which lead to perdition, evil doctrines and a corrupt life. Lest we fall into unholy doctrines, we must love God; so that we do not lead a corrupt life, we must love our neighbor (Levit. 19:18). For he who loves his neighbor fulfills all the commandments, and he who fulfills all the commandments, loves God. So by means of each other these two commandments are welded together and united, containing within themselves all the other commandments. For who is it that loves God and his neighbor, but also steals, or bears grudges, or commits adultery, or murders, or fornicates? This lawyer, then, at the onset came to test Him but then, hearing Christ’s answer, he amended his ways, and the Lord praised him, as Mark also says that Jesus looked at him with love, and said, "Thou art not far from the kingdom of heaven" (Mk. 12:34).
