But there has been some debate about this matter. For example, Scott G. Brown (while defending the authenticity of Secret Mark) disagrees with Smith that the scene is a reference to baptism. He thinks this is to profoundly misinterpret the text, and he argues that if the story really had been about baptism, it would not have mentioned only teaching, but also water or disrobing and immersion. He adds that "the young man's linen sheet has baptismal connotations, but the text discourages every attempt to perceive Jesus literally baptizing him." Stephen Carlson agrees that Brown's reading is more plausible than Smith's. The idea that Jesus practiced baptism is absent from the Synoptic Gospels, though it is introduced in the Gospel of John.
