Reply Obj. 1: The devil and Antichrist are not two heads, but one; since Antichrist is called the head, inasmuch as the wickedness of the devil is most fully impressed on him. Hence, on 2 Thess. 2:4, "Showing himself as if he were God," a gloss says: "The head of all the wicked, namely the devil, who is king over all the children of pride will be in him." Now he is said to be in him not by personal union, nor by indwelling, since "the Trinity alone dwells in the mind" (as is said De Eccles. Dogm. lxxxiii), but by the effect of wickedness.
Reply Obj. 2: As the head of Christ is God, and yet He is the Head of the Church, as was said above (A. 1, ad 2), so likewise Antichrist is a member of the devil and yet is head of the wicked.
Reply Obj. 3: Antichrist is said to be the head of all the wicked not by a likeness of influence, but by a likeness of perfection. For in him the devil, as it were, brings his wickedness to a head, in the same way that anyone is said to bring his purpose to a head when he executes it. _______________________
QUESTION 9
OF CHRIST'S KNOWLEDGE IN GENERAL
(In Four Articles)
We must now consider Christ's knowledge; concerning which the consideration will be twofold. First, of Christ's knowledge in general; secondly, of each particular kind of knowledge He had.
Under the first head there are four points of inquiry:
(1) Whether Christ had any knowledge besides the Divine?
(2) Whether He had the knowledge which the blessed or comprehensors have?
(3) Whether He had an imprinted or infused knowledge?
