Origen
Catena Aurea · Lukasevangelium 22
Then came the day of unleavened bread, when the Passover must be killed. And he sent Peter and John, saying, Go and prepare us the Passover, that we may eat. And they said unto him, Where wilt thou that we prepare? And he said unto them, Behold, when ye are entered into the city, there shall a man meet you, bearing a pitcher of water; follow him into the house where he entereth in. And ye shall say unto the goodman of the house, The Master saith unto thee, Where is the guestchamber, where I shall eat the Passover with my disciples? And he shall shew you a large upper room furnished: there make ready. And they went, and found as he had said unto them: and they made ready the Passover.
(ut sup.) But we should know that they who are taken up with banquetings and worldly cares do not ascend into that upper part of the house, and therefore do not keep the Passover with Jesus. For after the words of the disciples wherewith they questioned the goodman of the house, (that is, the understanding,) the Divine Person came into that house to feast there with His disciples.
