Theophylact of Ohrid
Catena Aurea · Lukasevangelium 24
Then opened he their understanding, that they might understand the Scriptures, And said unto them, Thus it is written, and thus it behoved Christ to suffer, and to rise from the dead the third day: And that repentance and remission of sins should be preached in his name among all nations, beginning at Jerusalem. And ye are witnesses of these things. And, behold, I send the promise of my Father upon you: but tarry ye in the city of Jerusalem, until ye be endued with power from on high.
But herein that He says, Repentance and remission of sins, He also makes mention of baptism, in which by the putting off of our past sins there follows pardon of iniquity. But how must we understand baptism to be performed in the name of Christ alone, whereas in another place He commands it to be in the name of the Father, and the Son, and the Holy Ghost. First indeed we say that it is not meant that baptism is administered in Christ’s name alone, but that a person is baptized with the baptism of Christ, that is, spiritually, not Judaically, nor with the baptism, wherewith John baptized unto repentance only, but unto the participation of the blessed Spirit; as Christ also when baptized in Jordan manifested the Holy Spirit in the form of a dove. Moreover you must understand baptism in Christ’s name to be in His death. For as He after death rose again on the third day, so we also are three times dipped in the water, and fitly brought out again, receiving thereby an earnest of the immortality of the Spirit. This name of Christ also contains in itself both the Father as the Anointer, and the Spirit as the Anointing, and the Son asthe Anointed, that is, in His human nature. But it was fitting that the race of man should no longer be divided into Jews and Gentiles, and therefore that He might unite all in one, He commanded that their preaching should begin at Jerusalem, but be finished with the Gentiles. Hence it follows, Beginning at Jerusalem. (Rom. 3:2, Rom. 9:4.)
