Catena Aurea on Luke 3:21–22: John Chrysostom

Now there was a Jewish baptism which removed the pollutions of the flesh, not the guilt of the conscience; but our baptism parts us from sin, washes the soul, and gives us largely the outpouring of the Spirit. But John’s baptism was more excellent than the Jewish; for it did not bring men to the observance of bodily purifications, but taught them to turn from sin to virtue. But it was inferior to our baptism, in that it conveyed not the Holy Spirit, nor shewed forth the remission which is by grace, for there was a certain end as it were of each baptism. But neither by the Jewish nor our own baptism was Christ baptized, for He needed not the pardon of sins, nor was that flesh destitute of the Holy Spirit which from the very beginning was conceived by the Holy Spirit; He was baptized by the baptism of John, that from the very nature of the baptism, you might know that He was not baptized because He needed the gift of the Spirit. But he says, being baptized and praying, that you might consider how fitting to one who has received baptism is constant prayer.
