Note 5 — Chapter XIII · Epistle to the Hebrews (A Sequel to Sophia Solomontos).
Reading edition
It is, I think, an indication of the nearness of the “Gospel according to the Hebrews” to the Apostolic Age that a sort of caveat is there recorded against the possible implication that the baptism of Jesus was for remission of sins. “He said to them, Wherein have I sinned that I should go and be baptized by him?” The whole passage is quoted on a farther page, but it may be stated here that the descending dove certifies the sinlessness of Jesus before his baptism. The Synoptics introduce the dove after the baptism. The significance of the scene was thus lost.
