Gregory the Great
Catena Aurea · Markusevangelium 16
Afterward he appeared unto the eleven as they sat at meat, and upbraided them with their unbelief and hardness of heart, because they believed not them which had seen him after he was risen. And he said unto them, Go ye into all the world, and preach the Gospel to every creature. He that believeth and is baptized shall be saved; but he that believed not shall be damned. And these signs shall follow them that believe; In my name shall they cast out devils; they shall speak with new tongues; They shall take up serpents; and if they drink any deadly thing, it shall not hurt them; they shall lay hands on the sick, and they shall recover.
(ubi sup.) We should observe that Luke says in the Acts, As he2 was eating with them he commanded that they should not depart from Jerusalem, and shortly afterwards, while they beheld he was taken up. For He ate, and then ascended, that by the act of eating, the truth of the flesh might be declared; wherefore it is also here said, that he appeared to them for the last time as they sat at meat.
