Bede the Venerable — as excerpted in the Catena Aurea on Mark 14:43-52

“(ubi sup.) In this is fulfilled the word, which the Lord had spoken, that all His disciples should be offended in Him that same night. There follows: And there followed him a certain young man, having a linen cloth cast about his naked body, that is, he had no other clothing but this linen cloth. It goes on: And they laid hold on him, and he left the linen cloth, and fled from them naked. That is, he fled from them, whose presence and whose deeds he abhorred, not from the Lord, for whom his love remained fixed in his mind, when absent from Him in body.”
