John Chrysostom
He calls them while actually working at their employment, to shew that to follow Him ought to be preferred to all occupations. They were just then casting a net into the sea, which agreed with their future office.
To so great a promise they trusted, and believed that they should catch others by those same words by which themselves had been caught.
It is no small sign of goodness, to bear poverty easily, to live by honest labour, to be bound together by virtue of affection, to keep their poor father with them, and to toil in his service.
He made no promise to them when He called them, as He had to the former, for the obedience of the first had made the way plain for them. Besides, they had heard many things concerning Him, as being friends and townsmen of the others.
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.
Before He spoke or did any thing, Christ called Apostles, that neither word nor deed of His should be hid from their knowledge, so that they may afterwards say with confidence, What we have seen and heard, that we cannot but speak. (Acts 4:20.)
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along, the Devil by pleasure drawing them into sin where men devour one another as the stronger fishes do the weaker, withdrawn from hence they may live upon the land, being made members of Christ’s body.
These disciples did not follow Christ from desire of the honour of a doctor, but because they coveted the labour itself; they knew how precious is the soul of man, how pleasant to God is his salvation, and how great its reward.
These were their desires, for which they left all and followed; teaching us thereby that none can possess earthly things and perfectly attain to heavenly things.
Rightly did He thus build the foundations of the brotherhood of the Church on love, that from such roots a copious sap of love might flow to the branches; and that too on natural or human love, that nature as well as grace might bind their love more firmly. They were moreover brothers; and so did God in the Old Testament lay the foundations of His building on Moses and Aaron, brothers. But as the grace of the New Testament is more abundant than that of the Old, therefore the first people were built upon one pair of brethren, but the new people upon two. They were washing their nets, a proof of the extremest indigence; they repaired the old because they had not whence they should buy new.

And what shews their great filial piety, in this their great poverty they deserted not their father, but carried him with them in their vessel, not that he might aid in their labour, but have the enjoyment of his sons’ presence.
We may not dare to consider the former disciples as more quick to preach, because they were casting their nets; and these latter as less active, because they were yet making ready only; for it is Christ alone that may know their differences. But perhaps we may say that the first were casting their nets, because Peter preached the Gospel, but committed it not to paper—the others were making ready their nets, because John composed a Gospel. He called them together, for by their abode they were fellow-townsmen, in affection attached, in profession agreed, and united by brotherly tenderness. He called them then at once, that united by so many common blessings they might not be separated by a separate call.
There are three things which we must leave who would come to Christ; carnal actions, which are signified in the fishing nets; worldly substance, in the ship; parents, which are signified in their father. They left their own vessel, that they might become governors of the vessel of the Church; they left their nets, as having no longer to draw out fishes on to the earthly shore, but men to the heavenly; they left their father, that they might become the spiritual fathers of all.
