Gospels. According to the evolutionary model, the earliest Christians believed that Jesus was a human who was exalted, and thus adopted as God's Son, when he was resurrected, signaling the nearness of the Kingdom of God, when all dead would be resurrected and the righteous exalted. Adoptionist concepts can be found in the Gospel of Mark. As Daniel Johansson notes, a majority consensus holds Mark's Jesus as "an exalted, but merely human figure", especially when read in the apparent context of Jewish beliefs. Later beliefs shifted the exaltation to his baptism, birth, and subsequently to the idea of his eternal existence, as witnessed in the Gospel of John. Mark shifted the moment of when Jesus became the son to the baptism of Jesus, and later still Matthew and Luke shifted it to the moment of the divine conception, and finally John declared that Jesus had been with God from the beginning: "In the beginning was the Word". One notable passage that may have been cited by early adoptionists was what exactly God said at Jesus's baptism; three different versions are recorded. One of them, found in the Codex Bezae version of Luke 3:22, is "You are my son; today I have begotten you." This seems to be quoted in Acts 13:32–33 as well (in all manuscripts, not just Bezae). Quotes from second and third century Christian writers almost always use this variant as well, with many fourth and fifth century writers continuing to use it, if occasionally with embarrassment; Augustine cites the line, for example, but clarifies God meant an eternal "today". Ehrman speculates that Orthodox scribes of the fourth and fifth century changed the passage in Luke to align with the version in Mark as a defense against adoptionists citing the passage in their favor. Since the 1970s, the late datings for the development of a "high Christology" have been contested, and a majority of scholars argue that this "high Christology" existed already before the writings of Paul. This "incarnation Christology" or "high Christology" did not evolve over a longer time, but was a "big bang" of ideas which were already present at the start of Christianity, and took further shape in the first few decades of the church, as witnessed in the writings of Paul. According to Ehrman, these two Christologies existed alongside each other, calling the "low Christology" an "adoptionist Christology, and "the "high Christology" an "incarnation
