De Sacrificiis Abelis Et Caini

It happens then, that there are two opinions contrary to and at variance with one another; the one of which commits everything to the mind as the leader of all reasoning, or feeling, or moving, or being stationary; and the other, attributing to God all the consequent work of creation as his own. Now the symbol of the former of these is Cain, which name, being interpreted means, "possession," from his appearing to possess all things; and the symbol of the other is Abel; for this name, being interpreted, means "referring to God."
