Gregory the Great, on Job 2:7

“So Satan went forth from the presence Of the Lord, and struck Job with a very grievous ulcer, from the sole of the foot even to the top of his head:”

“ALLEGORICAL INTERPRETATION. So went Satan forth from the presence of the Lord, and smote Job with sore boils, from the sole of his foot unto his crown. No one entereth into this life of the Elect, that has not undergone the contradictions of this enemy. And they all have proved themselves the members of our Redeemer, who, from the first beginning of the world, whilst living righteously, have suffered wrongs. Did not Abel prove himself His member, who not only in propitiating God by his sacrifice, but also by dying without a word, was a figure of Him, of whom it is written, He is brought as a lamb to the slaughter, and as a sheep before her shearers is dumb, so He openeth not His mouth. Thus from the very beginning of the world he strove to vanquish the Body of our Redeemer; and thus He inflicted wounds 'from the sole of the foot to His crown,' in that beginning with mere men, he came to the very Head of the Church in his raging efforts.”
