Basil the Great
Catena Aurea · Lukasevangelium 10
And the seventy returned again with joy, saying, Lord, even the devils are subject unto us through thy name. And he said unto them, I beheld Satan as lightning fall from heaven. Behold, I give unto you power to tread on serpents and scorpions, and over all the power of the enemy: and nothing shall by any means hurt you. Notwithstanding in this rejoice not, that the spirits are subject unto you; but rather rejoice, because your names are written in heaven.
(Hom. Quod Deus non est auctor mali.) He is called Satan, because he is an enemy to God, (for this the Hebrew word signifies,) but he is called the Devil, because he assists us in doing evil, and is an accuser. His nature is incorporeal, his abode in the air.
