Theophylact of Ohrid — as excerpted in the Catena Aurea on Luke 24:41-44

“The things eaten seem also to contain another mystery. For in that He ate part of a broiled fish, He signifies that having burnt by the fire of His own divinity our nature swimming in the sea of this life, and dried up the moisture which it had contracted from the waves, He made it divine food; and that which was before abominable He prepared to be a sweet offering to God, which the honeycomb signifies. Or by the broiled fish He signifies the active life, drying up the moisture with the coals of labour, but by the honeycomb, the contemplative life on account of the sweetness of the oracles of God.”
