Bede the Venerable
Catena Aurea · Markusevangelium 1
Now as he walked by the sea of Galilee, he saw Simon and Andrew his brother casting a net into the sea: for they were fishers. And Jesus said unto them, Come ye after me, and I will make you to become fishers of men. And straightway they forsook their nets, and followed him. And when he had gone a little farther thence, he saw James the son of Zebedee, and John his brother, who also were in the ship mending their nets. And straightway he called them: and they left their father Zebedee in the ship with the hired servants, and went after him.
(ubi sup.) It may be asked, how he could call two fishers from each of the boats, (first, Peter and Andrew, then having gone a little further, the two others, sons of Zebedee,) when Luke says that James and John were called to help Peter and Andrew, and that it was to Peter only that Christ said, Fear not, from this time thou shalt catch men; (Luke 5:10) he also says, that at the same time, when they had brought their ships to land, they followed him. We must therefore understand that that transaction which Luke intimates happened first, and afterwards that they, as their custom was, had returned to their fishing. So that what Mark here relates happened afterwards; for in this case they followed the Lord, without drawing their boats ashore, (which they would have done had they meant to return,) and followed Him, as one calling them, and ordering them to follow.
