John 6:9

And I think (and let the lover of wisdom look out for something better) that by the five barley loaves are signified the five-fold book of the all-wise Moses, that is, the whole Law, bringing in as it were coarser food, that by the letter and history. For this the barley hints at. But by the little fishes is signified the food got through the fishermen, that is, the more delicate books of the disciples of the Saviour; and these two (he says), the apostolic and Evangelic preaching, shine forth among us. And both these are draughts and spiritual writings of the fishermen. The Saviour therefore mingling the new with the old, by the Law and the teachings of the New Testament nourishes the souls of them that believe on Him, unto life, plainly eternal life.

(Hom. xlii. 2.) And let those of us, who are given to pleasure, observe the plain and abstemious eating of those great and wonderful men.

But John saith also, that they were "barley loaves," not mentioning it without object, but teaching us to trample under foot the pride of costly living. Such was the diet of the prophets also.

"Andrew, Simon's brother, said, There is a lad here, which hath five barley loaves, and two small fishes: but what are they among so many?" Andrew is higher minded than Philip, yet had not he attained to everything. Yet I do not think that he spake without an object, but as having heard of the miracles of the Prophets, and how Elisha wrought a sign with the loaves; on this account he mounted to a certain height, but could not attain to the very top.

What follows also expresses great weakness. For after saying, "hath five barley loaves," he addeth, "but what are they among so many?" He supposed that the Worker of the miracle would make less out of less, and more out of more. But this was not the case, for it was alike easy to Him to cause bread to spring forth from more and from less, since He needed no subject-matter. But in order that the creation might not seem foreign to His Wisdom, as afterwards slanderers and those affected with the disease of Marcion said, He used the creation itself as a groundwork for His marvels.

He both thinks and reasons akin to Philip, and is convicted of having a kindred apprehension of the Saviour Christ. For neither considering the power, nor yet led by the greatness of His preceding works unto Jesus' being able for all things, and that most easily; he points out what the lad has, but is evidently weak in faith: for what are these (he says) among so many? Albeit (for we must say it) in no unready way but resolutely rather ought he to go forth to the memory of those things which had been already miraculously wrought, and to consider that it was a work by no means strange or foreign from Him Who had transformed into wine the nature of water, had healed the palsied and driven away so great an infirmity by one word, that He, I say, should create food of that which had no being, and multiply Divinely the exceeding little that was found ready to hand. For the Authority that wrought in the one, how should it not be able to work in the other? Wherefore the pair of disciples answered more feebly than was meet. But herein we must consider this again. For those things which appear to have been little falls in the Saints, are oftentimes not without their share of profit, but have something wrapt up with them, helpful to the nature of that in regard to which is the charge of their apparent infirmity. For the above mentioned holy disciples, having considered, and openly said, one, that Two hundred pennyworth of bread is not sufficient for them that every one may take a little, the other, of the five loaves and two little fishes, that what are these among so many? raise the marvel to its height, and make the Might of the Saviour most marked, indicating by their own words the multitude that but now was to be filled, and the strength of their unbelief is converted into good testimony unto Christ. […]

(de Con. Evang. ii. c. xlvi) Andrew's suggestion about the five loaves and two fishes, is given as coming from the disciples in general, in the other Evangelists, and the plural number is used.

Andrew is in the same perplexity that Philip is; only he has rather higher notions of our Lord: There is a lad here which hath five barley loaves and two small fishes. This passage confounds the Manicheans, who say that bread and all such things were created by an evil Deity. The Son of the good God, Jesus Christ, multiplied the loaves. Therefore they could not have been naturally evil; a good God would never have multiplied what was evil.

(Hom. in Luc. c. vi.) Barley is the food of cattle and slaves: and the old law was given to slaves and cattle, i. e. to carnal men. Or, by the two fishes are meant the saying or writings of the Prophets, and the Psalmist. And whereas the number five refers to the five senses, a thousand stands for perfection. But those who strive to obtain the perfect government of their five senses, are called men, in consequence of their superior powers: they have no womanly weaknesses; but by a sober and chaste life, earn the sweet refreshment of heavenly wisdom. (Aug. xxiv. 5) And well is it said, But what are these among so many? The Law was of little avail, till He took it into His hand, i. e. fulfilled it, and gave it a spiritual meaning. The Law made nothing perfect. (Heb. 7:19)

Andrew, however, seems to sense that a miracle is going to take place. Perhaps he recalled the miracle performed by Elisha with the barley loaves, when he fed a hundred men with twenty loaves (2 Kgs 4:42). And so he says, There is a boy …

Having tested Philip as to whether he had faith, and having discovered that he was not yet free from human weakness, He finds Andrew to be the same, although his understanding was somewhat higher than Philip's. Philip said that "two hundred denarii worth of bread …

"There is a boy here who has five barley loaves and two fish": so many loaves, he says, we have, but they are not sufficient; therefore he says: "But what are these among so many?" In this is noted the remarkable poverty of the Lord …

There is a lad here,.... Who either belonged to Christ and his disciples, and was employed to carry their provisions for them; which, if so, shows how meanly Christ and his disciples lived; or he belonged to some in the multitude; or rather he came here to sell what he had got: which hath five barley loaves.

There is a lad here - Παιδαριον, a little boy, or servant, probably one who carried the apostles’ provisions, or who came on purpose to sell his bread and fish. Five barley loaves - Barley scarcely bore one-third of the value of wheat in the east: see Rev 6:6. That it was a very mean fare appears from Eze 13:19, where the false prophetesses are said to pollute the name of God for handfuls of barley, i.e. for the meanest reward.

These verses describe one of our Lord's most remarkable miracles. Of all the great works that He did, none was done so publicly as this, and before so many witnesses. Of all the miracles related in the Gospels, this is the only one which all the four Gospel-writers alike record. This fact alone (like the four times repeated account of the crucifixion and resurrection) is enough to show that it is a miracle demanding special attention. We have, for one thing, in this miracle, a lesson about Christ's almighty power.

These verses describe one of our Lord's most remarkable miracles. Of all the great works that He did, none was done so publicly as this, and before so many witnesses.

This fact alone (like the four times repeated account of the crucifixion and resurrection) is enough to show that it is a miracle demanding special attention. We have, for one thing, in this miracle, a lesson about Christ's almighty power. We see our Lord feeding five thousand men with "five barley loaves and two small fish." We see clear proof that a miraculous event took place in the "twelve baskets of fragments" that remained after all had eaten. Creative power was manifestly exercised. Food was called into existence that did not exist before. In healing the sick, and raising the dead, something was amended or restored that had already existed. In feeding five thousand men with five loaves, something must have been created which before had no existence. Such a history as this ought to be specially instructive and encouraging to all who endeavor to do good to souls. It shows us the Lord Jesus "able to save to the uttermost." He is One who has all power over dead hearts. Not only can He mend that which is broken—build up that which is ruined—heal that which is sick—strengthen that which is weak. He can do even greater things than these. He can call into being that which was not before, and call it out of nothing. We must never despair of any one being saved. So long as there is life there is hope. Reason and sense may say that some poor sinner is too hardened, or too old to be converted. Faith will reply—"Our Master can create as well as renew . With a Savior who, by His Spirit, can create a new heart, nothing is impossible."
