Matthew 14:17

But the Lord answered, They have no need to go, showing that those whom He heals have no need of the food of mercenary doctrine, and have no necessity to return to Judæa to buy food; and He commands the Apostles that they give them food. Did He not know then that there was nothing to give them? But there was a complete series of types to be set forth; for as yet it was not given the Apostles to make and minister the heavenly bread, the food of eternal life; and their answer thus belongs to the chain of spiritual interpretation; they were as yet confined to the five loaves, that is, the five books of the Law, and the two fishes, that is, the preaching of the Prophets and of John.

These therefore the Apostles first set forth, because they were yet in these things; and from these things the preaching of the Gospel grows to its more abundant strength and virtue. Then the people is commanded to sit down upon the grass, as no longer lying upon the ground, but resting upon the Law, each one reposing upon the fruit of his own works as upon the grass of the earth.

When the disciples advised that the crowds be sent away into the neighboring villages to buy food, he answered, "They do not need to go away." This signaled that these people whom he healed with the food of teaching, teaching that was not for sale, had no need to go back to Judea and buy food. He ordered the apostles to give them something to eat.But was Jesus unaware there was nothing to give? Did he not know the disciples possessed a limited amount of food? He could read their minds, so he knew. We are invited to explain things by reasoning according to types. It was not yet granted to the apostles to make and administer heavenly bread for the food of eternal life. Yet their response reflected an ordered reasoning about types: they had only five loaves and two fish. This means that up to then they depended on five loaves—that is, the five books of the law. And two fish nourished them—that is, the preaching of the prophets and of John. For in the works of the law there was life just as there is life from bread, but the preaching of John and the prophets restored hope to human life by virtue of water. Therefore the apostles offered these things first, because that was the level of their understanding at the time. From these modest beginnings the preaching of the gospel has proceeded from them, from these same apostles, until it has grown into an immense power.

Wherein He calls the Apostles to breaking of bread, that the greatness of the miracle might be more evident by their testimony that they had none.

But He is about to feed them also. And He doth not this of Himself, but waits to be entreated; on every occasion, as I have said, maintaining this rule, not to spring onward to His miracles, preventing them, but upon some call. And why did none of the multitude come near and speak for them? They reverenced Him exceedingly, and felt not even their hunger, through their longing to stay with Him. Neither indeed do His disciples, when they were come to Him, say, "Feed them;" for as yet they were rather in an imperfect state; but what? "And when it was evening," it is said, "His disciples came to Him, saying, This is a desert place, and the time is now passed; send the multitude away, that they may go and buy themselves victuals." For if even after the miracle they forgot what had been done, and after the baskets, supposed Him to be speaking of loaves, when He gave the name of "leaven" to the doctrine of the Pharisees; much less, when they had never yet had experience of such a miracle, would they have expected any such thing. And yet He had made a beginning by actually healing many sick; but nevertheless, not even from this did they expect the miracle of the loaves; so imperfect were they as yet. But mark thou, I pray, the Teacher's skill, how distinctly He summons them on towards believing. For He said not at once, "I feed them;" which indeed would not have been easily received; but what? "But Jesus," so it is written, "said unto them, They need not depart; give ye them to eat." He said not, "I give them," but, "Give ye them;" for as yet their regard to Him was as to a man. […]
