Matthew 4:19

The operations of their secular craft were a prophecy of their future dignity. As he who casts his net into the water knows not what fishes he shall take, so the teacher casts the net of the divine word upon the people, not knowing who among them will come to God. Those whom God shall stir abide in his doctrine. Fishers of men, that is, teachers, that with the net of God's word you may catch men out of this world of storm and danger, in which men do not walk but are rather borne along, the Devil by pleasure drawing them into sin where men devour one another as the stronger fishes do the weaker, withdrawn from hence they may live upon the land, being made members of Christ's body.

(interlin.) Follow me, not so much with your feet as in your hearts and your life.

By this that they left their occupation and their father's house we are taught, that when we would follow Christ we should not be holden of the cares of secular life, or of the society of the paternal mansion. Or, the number that was to be of the Evangelists is figured.

And yet John saith that they were called in another manner. Whence it is evident that this was a second call; and from many things one may perceive this. For there it is said, that they came to Him when "John was not yet cast into prison;" but here, after he was in confinement. And there Andrew calls Peter, but here Jesus calls both. And John saith, Jesus seeing Simon coming, saith, "Thou art Simon, the Son of Jona, thou shalt be called Cephas, which is by interpretation, a stone." But Matthew saith that he was already called by that name; for his words are, "Seeing Simon that was called Peter." And from the place whence they were called, and from many other things, one may perceive this; and from their ready obedience, and abandonment of all. For now they were well instructed beforehand. Thus, in the other case, Andrew is seen coming into His house, and hearing many things; but here, having heard one bare word, they followed immediately. Since neither was it unnatural for them to follow Him at the beginning, and then leave Him again and return anew to their own craft, when they saw both John thrown into prison, and Himself departing. Accordingly you see that He finds them actually fishing. But He neither forbad them at the first when minded to withdraw, nor having withdrawn themselves, did He let them go altogether; but He gave way when they started aside from Him, and comes again to win them back; which kind of thing is the great point in fishing.

(Serm. 197. 2.) He chose not kings, senators, philosophers, or orators, but he chose common, poor, and untaught fishermen. (Aug. Tract. in Joann. vii. 17.) Had one learned been chosen, he might have attributed the choice to the merit of his learning. But our Lord Jesus Christ, willing to bow the necks of the proud, sought not to gain fishermen by orators, but gained an Emperor by a fisherman. Great was Cyprian the pleader, but Peter the fisherman was before him. (Ev. ii. 17.) It might move enquiry, why John relates that near Jordan, not in Galilee, Andrew followed the Lord with another whose name he does not mention; and again, that Peter received that name from the Lord. Whereas the other three Evangelists write that they were call d rom their fishing, sufficiently agreeing with one another, especially Matthew and Mark; Luke not naming Andrew, who is however understood to have been in the same vessel with him. There is a further seeming discrepancy, that in Luke it is to Peter only that it is said, Henceforth thou shalt catch men; Matthew and Mark write that it was said to both. As to the different account in John, it should be carefully considered, and it will be found that it is a different time, place, and calling that is there spoken of. For Peter and Andrew had not so seen Jesus at the Jordan that they adhered inseparably ever after, but so as only to have known who He was, and wondering at Him to have gone their way. Perhaps he is returning back to something he had omitted, for he proceeds without marking any difference of time, As he walked by the sea of Galilee. It may be further asked, how Matthew and Mark relate that He called them separately two and two, when Luke relates that James and John being partners of Peter were called as it were to aid him, and bringing their barks to land followed Christ. We may then understand that the narrative of Luke relates to a prior time, after which they returned to their fishing as usual. For it had not been said to Peter that he should no more catch fishes, as he did do so again after the resurrection, but that he should catch men. Again, at a time after this happened that call of which Matthew and Mark speak; for they draw their ships to land to follow Him, not as careful to return again, but only anxious to follow Him when He bids them.
