Catena Aurea · Lukasevangelium 24
Then he said unto them, O fools, and slow of heart to believe all that the prophets have spoken: Ought not Christ to have suffered these things, and to enter into his glory? And beginning at Moses and all the prophets, he expounded unto them in all the Scriptures the things concerning himself. And they drew nigh unto the village, whither they went: and he made as though he would have gone further. But they constrained him, saying, Abide with us: for it is toward evening, and the day is far spent. And he went in to tarry with them. And it came to pass, as he sat at meat with them, he took bread, and blessed it, and brake, and gave to them. And their eyes were opened, and they knew him; and he vanished out of their sight. And they said one to another, Did not our heart burn within us, while he talked with us by the way, and while he opened to us the Scriptures? And they rose up the same hour, and returned to Jerusalem, and found the eleven gathered together, and them that were with them, Saying, The Lord is risen indeed, and hath appeared to Simon. And they told what things were done in the way, and how he was known of them in breaking of bread.
(ut sup.) Or because the Lord feigned as if He would go farther, when He was accompanying the disciples, expounding to them the sacred Scriptures, who knew not whether it was He, what does He mean to imply but that through the duty of hospitality men may arrive at a knowledge of Him; that when He has departed from mankind far above the heavens, He is still with those who perform this duty to His servants. He therefore holds to Christ, that He should not go far from him, whoever being taught in the word communicates in all good things to him who teaches. (Gal. 6:6.) For they were taught in the word when He expounded to them the Scriptures. And because they followed hospitality, Him whom they knew not in the expounding of the Scriptures, they know in the breaking of bread. For not the hearers of the law are just before God, but the doers of the law shall be justified. (Rom. 2:13.)
