Thomas Aquinas

“ Now a multitude ordained to one end, with distinct acts and duties, may be metaphorically called one body. But it is manifest that both men and angels are ordained to one end, which is the glory of the Divine fruition. Hence the mystical body of the Church consists not only of men but of angels. Now of all this multitude Christ is the Head, since He is nearer God, and shares His gifts more fully, not only than man, but even than angels ”

“ It would seem that Antichrist is not the head of the wicked. For there are not several heads of one body. But the devil is the head of the multitude of the wicked. Therefore Anti-christ is not their head. ”

“ Anti-christ 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. ”
