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.
(in Matt. 26:18.) But I think that the man who meets the disciples as they enter into the city, carrying a pitcher of water, was some servant of a master of a house, carrying water in an earthen vessel either for washing or for drinking. And this I think is Moses conveying the spiritual doctrine in fleshly histories. But they who follow him not, do not celebrate the Passover with Jesus. Let us then ascend with the Lord united to us, to the upper part in which is the guestchamber, which is shewn by the understanding, that is, the goodman of the house, to every one of the disciples of Christ. But this upper room of our house must be large enough to receive Jesus the Word of God, who is not comprehended but by those who are greater in comprehension. And this chamber must be made ready by the goodman of thehouse, (that is, the understanding,) for the Son of God, and it must be cleaned, wholly purged of the filth of malice. The master of the house also must not be any common person having a known name. Hence He says mystically in Matthew, Go ye to such a one.
