The Church Fathers on the Feeding of the Multitude

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.

— Augustine 

For although the Lord had the power to supply wine to those feasting, independently of any created substance, and to fill with food those who were hungry, he did not adopt this course; but, taking the loaves which the earth had produced, and giving thanks, and on the other occasion making water wine, he satisfied those who were reclining (at table), and gave drink to those who had been invited to the marriage; showing that the God who made the earth, and commanded it to bring forth fruit, who established the waters, and brought forth the fountains, was he who in these last times bestowed upon mankind, by his Son, the blessing of food and the favor of drink: the incomprehensible [acting thus] by means of the comprehensible, and the invisible by the visible; since there is none beyond him, but he exists in the bosom of the Father.

— Irenaeus 

He called his disciples, and asked what quantity of food they had with them. But they said that they had five loaves and two fishes in a wallet. . . . He himself broke the bread in pieces, and divided the flesh of the fishes, and in his hands both of them were increased. And when he had ordered the disciples to set them before the people, 5,000 men were satisfied, and moreover 12 baskets were filled from the fragments which remained. What can be more wonderful, either in narration or in action?

— Lactantius 

The feeding of the multitudes in the desert by Christ is worthy of all admiration. But it is also profitable in another way. We can plainly see that these new miracles are in harmony with those of ancient times. They are the acts of one and the same power. He rained manna in the desert upon the Israelites. He gave them bread from heaven. "Man did eat angels’ food," according to the words of praise in the Psalms. But look! He has again abundantly supplied food to those who needed food in the desert. He brought it down, as it were, from heaven. Multiplying that small amount of food many times and feeding so large a multitude, so to speak, with nothing, is like that first miracle.

— Cyril of Alexandria

He (multiplies loaves) not only once but also a second time, in order that we should know his strength. This strength by which he feeds the multitudes when he wishes and without bread finds its source in his divinity. He does this in order to bring them to believe that he himself is the one who earlier had fed Israel for 40 years in the wilderness. And Jesus not only fed them with a few loaves of bread, but he even produced a surplus of seven baskets, so that he might be shown as incomparably surpassing Elijah, who himself also caused a multiplication of the widow’s small quantity of oil and flour.
