Thomas Aquinas

“ According to some, knowledge and active power are not in the same ratio; for an active power flows from the very nature of the thing, inasmuch as action is considered to come forth from the agent; but knowledge is not always possessed by the very essence or form of the knower, since it may be had by assimilation of the knower to the thing known by the aid of received species. ”

“ Hence there would be no reason why the soul of Christ, as it can know all things by the similitudes of all things impressed upon it by God, cannot do these things by the same similitudes.
It has, therefore, to be further considered that what is received in the lower nature from the higher is possessed in an inferior manner; for heat is not received by water in the perfection and strength it had in fire. ”

“ Further, human nature was more perfect in Christ than in Adam, who had a body entirely subject to the soul, so that nothing could happen to the body against the will of the soul---and this on account of the original justice which it had in the state of innocence. Much more, therefore, had Christ's soul omnipotence with regard to His body. ”

“ But power is said to have been given Him, by reason of the union whereby it was brought about that a Man was omnipotent, as was said above (A [1] , ad 1) . And although this was made known to the angels before the Resurrection, yet after the Resurrection it was made known to all men, as Remigius says (cf. Catena Aurea) . Now, "things are said to happen when they are made known" [*Hugh of St. Victor: Qq. in Ep. ad Philip.] . Hence after the Resurrection our Lord says "that all power is given" to Him "in heaven and on earth." ”

“ So, too, the similitudes of things infused into Christ's soul do not equal the Divine power in acting, i.e. so as to do all that God can do, or to do in the same manner as God does, Who acts with an infinite might whereof the creature is not capable. Now there is no thing, to know which in some way an infinite power is needed, although a certain kind of knowledge belongs to an infinite power ”

“ By union with the Person, the Man receives omnipotence in time, which the Son of God had from eternity; the result of which union is that as the Man is said to be God, so is He said to be omnipotent; not that the omnipotence of the Man is distinct (as neither is His Godhead) from that of the Son of God, but because there is one Person of God and man. ”

“ But this reason seems not to suffice, because even as we may understand by a likeness obtained from another, so also may we act by a form obtained from another, as water or iron heats, by heat borrowed from fire. ”

“ If the imagination be strong, the body obeys naturally in some things, e.g. as regards falling from a beam set on high, since the imagination was formed to be a principle of local motion, as is said De Anima iii, 9,10. ”
