“The prophet Zechariah speaks of Satan as an angel whose office it is to accuse and to demand the punishment of the wicked. In the Book of Job, where the most poetical and grandest picture of the Evil One is found, Satan appears as a malicious servant of God, who enjoys performing the functions of a tempter, torturer, and avenger. He accuses unjustly, like a State’s attorney who prosecutes from a mere habit of prosecution, and delights in convicting even the innocent, while God’s justice and goodness are not called in question. It is noteworthy that Satan, in the canonical books of the Old Testament, is an adversary of man, but not of God; he is a subject of God and God’s faithful servant.”
