John Chrysostom
Catena Aurea · Johannesevangelium 21
Jesus saith unto them, Come and dine. And none of the disciples durst ask him, Who art thou? knowing that it was the Lord. Jesus then cometh, and taketh bread, and giveth them, and fish likewise. This is now the third time that Jesus shewed himself to his disciples, after that he was risen from the dead. And none of His disciples durst ask Him, who art Thou? knowing that it was the Lord.
(Hom. lxxxvii) He means that they had not confidence to talk to Him, as before, but sat looking at Him in silence and awe, absorbed in regarding His altered and now supernatural form, and unwilling to ask any question. Knowing that it was the Lord, they were in fear, and only ate what, inexercise of His great power, He had created. He again does not look up to heaven, or do any thing after a human sort, thus shewing that His former acts of that kind were done only in condescension: Jesus then cometh, and taketh bread, and giveth them, and fish likewise.
