Origen
Catena Aurea · Johannesevangelium 1
And this is the record of John, when the Jews sent priests and Levites from Jerusalem to ask him, Who art thou? And he confessed, and denied not; but confessed, I am not the Christ. And they asked him, What then? Art thou Elias? And he saith, I am not. Art thou that prophet? And he answered, No. Then said they unto him, Who art thou? that we may give an answer to them that sent us. What sayest thou of thyself? He said, I am the voice of one crying in the wilderness, Make straight the way of the Lord, as said the prophet Esaias.
(t. vi. c. 4) The Jews of Jerusalem, as being of kin to the Baptist, who was of the priestly stock, send Priests and Levites to ask him who he is; (c. 6). that is, men considered to hold a superior rank to the rest of their order, by God’s election, and coming from that favoured above all cities, Jerusalem. Such is the reverential way in which they interrogate John. We read of no such proceeding towards Christ: but what the Jews did to John, John in turn does to Christ, when he asks Him, through His disciples, Art thou He that should come, (Luke 7:20) or look we for another?
