John Chrysostom — as excerpted in the Catena Aurea on John 21:1-11

“(Hom. lxxxvii) He says, Afterwards, because He did not go continually with His disciples as before; and, manifested Himself, because His body being incorruptible, it was a condescension to allow Himself to be seen. He mentions the place, to shew that our Lord had taken away a good deal of their fear, and that they no longer kept within doors, though they had gone to Galilee to avoid the persecution of the Jews.”
