Whether the Devil is the Head of all the Wicked?
Objection 1: It would seem that the devil is not the head of the wicked. For it belongs to the head to diffuse sense and movement into the members, as a gloss says, on Eph. 1:22, "And made Him head," etc. But the devil has no power of spreading the evil of sin, which proceeds from the will of the sinner. Therefore the devil cannot be called the head of the wicked. Objection 2: Further, by every sin a man is made evil. But not every sin is from the devil; and this is plain as regards the demons, who …

Dei xx, 16): "In my opinion no man knows of what kind is the everlasting fire, unless the Spirit of God has revealed it to anyone." But all or nearly all know the nature of this fire of ours. Therefore that fire is not of the same species as this. Objection 2: Further, Gregory commenting on Job 10:26, "A fire that is not kindled shall devour him," says (Moral. xv): …

The Desire of the Righteous Granted;
OR, A DISCOURSE OF THE RIGHTEOUS MAN'S DESIRES. ADVERTISEMENT BY THE EDITOR As the tree is known by its fruit, so is the state of a man's heart known by his desires. The desires of the righteous are the touchstone or standard of Christian sincerity--the evidence of the new birth--the spiritual barometer of faith and grace--and the springs of obedience.
