John 6:11

(iii. de Trin. c. 18) Five loaves are then set before the multitude, and broken. The broken portions pass through into the hands of those who break, that from which they are broken all the time not at all diminishing. And yet there they are, the bits taken from it, in the hands of the persons breakingd. There is no catching by eye or touch the miraculous operation: that is, which was not, that is seen, which is not understood. It only remains for us to believe that God can do all things.

But why when He was about to restore the paralytic did He not pray, nor when He was raising the dead, or bridling the sea, while He doth so here over the loaves? It was to show that when we begin our meals, we ought to give thanks unto God. Moreover, He doth it especially in a lesser matter, that thou mayest learn that He doth it not as having any need; for were this the case, much more would He have done so in greater things; but when He did them by His own authority, it is clear that it was through condescension that He acted as He did in the case of the lesser.

"And He gave to them that were set down, and they were filled." Seest thou how great is the interval between the servants and the Master? They having grace by measure, wrought their miracles accordingly, but God, who acteth with free power, did all most abundantly.

(Tr. xxiv. s. 1.) He multiplied in His hands the five loaves, just as He produces harvest out of a few grains. There was a power in the hands of Christ; and those five loaves were, as it were, seeds, not indeed committed to the earth, but multiplied by Him who made the earth. (Tr. xxiv. s. 5) By the act of breaking He multiplied the five loaves. The five books of Moses, when expounded by breaking, i. e. unfolding them, made many books. (lib. lxxxiii. Quæst. qu. 61) Our Lord by breaking, as it were, what was hard in the Law, and opening what was shut, that time when He opened the Scriptures to the disciples after the resurrection, brought the Law out in its full meaning.

For who now feeds the whole world, but He who out of a few seeds creates the harvests? He wrought, therefore, as God. For by the same power whereby He multiplies the stores of grain from a few seeds, did He multiply in His hands the five loaves. For power was in the hands of Christ, and those five loaves were as seeds, not indeed committed to the earth, but multiplied by Him who made the earth.
