A moment ago I learned of Kermit Zarley who is a retired professional golfer and now is an author of books on biblical studies. He apparently is a progressive Christian who no longer believes in the trinity doctrine and apparently is now a unitarian in regards to his concept of the biblical God (see https://21stcr.org/author/kermit-zarley/ ). Though he believes "that Jesus never thought he was God or claimed to be God", he nonetheless disagrees with a number of Bart Ehrman's ideas. He also believes some things about Jesus which the WT also believes. At https://www.patheos.com/blogs/kermitzarleyblog/author/kermitzarleyblog/ Zarley says the following.
"Ehrman begins his Introduction by saying (p. 3), “The idea that Jesus is God … was the view of the very earliest Christians soon after Jesus’s death.” I strongly disagree. I show in 322 pages in my RJC book that nowhere does the NT declare that Jesus is God, and I treat the critical biblical texts in depth. Ehrman further surmises (p. 6) “how Jesus came to be considered God. The short answer is that it all had to do with his follower’s belief that he had been raised from the dead.” WOW!
This is the thesis of Ehrman’s book, How Jesus Became God. Some Christians have also believed this. But it is irrational and antithetical to Judaism. Thus, it is highly unlikely that the early Jewish Christians believed that. Tom (N.T.) Wright and other leading NT scholars have convincingly refuted this argument. Most Jews during Jesus’ time, including him and his contemporaries, the Pharisees and Essenes, believed in the future resurrection of God’s people, and they certainly did not think that would make them gods.
... Ehrman ... takes the typical position of historical-critical scholars about Jesus and the NT gospels. They correctly state that, according to the synoptic gospels, Jesus did not believe he was God or say he was God, and his early disciples didn’t believe he was God either. But Ehrman errs in saying the Gospel of John identifies Jesus as God. (See pp. 124-25, 248). About Ehrmans’ quotes of Jesus in John 8.58, Jesus therein didn’t mean he preexisted but that he was superior to Abraham. The prior context of John 10.30 shows that Jesus meant he and the Father work together in unity as “one,” not that they are one in essence as some church fathers asserted. (Cf. “one” in John 17.11, 22-23). And Jesus saying, “Whoever has seen me has seen the Father” (John 14.9), does not mean he is God or the Father since he then explained it to mean, “I am in the Father and the Father is in me” (v. 11; cf. 10.38). Scholars call this the Mutual Indwellling, and many people have confused it with Jesus being identified as God. Yet Ehrman is right in saying that if Jesus publicly said he was God, Matthew, Mark, and Luke would have mentioned it in their gospels. Moreover, Jews would have argued with him about it far more than that he was the Messiah. Ehrman rightly says later that being a Jew (p. 98), “Jesus would have believed that there was one true God.”
... As stated above, Ehrman says that right after Jesus’ death, the early Jewish Christians began to believe that Jesus was God. On the contrary, I maintain that the NT does not say Jesus was God, so that it was not until the second century, after the apostolic era and the writing of the NT, that some Christians began to say Jesus was/is God. But for the next two centuries they said his divinity/deity was less than that of the Father, making Jesus essentially subordinate to God. It was not until the Nicene Creed, in 325, that Christians declared Jesus is God just as much as the Father is. And only in the latter half of the fourth century did Catholic Church officials construct the doctrine of the Trinity that we know about today.
... In Chapter 2, Ehrman says again of early Christians (p. 49-50), “How could they say that Jesus was God and still claim that there was only one God. If God was God and Jesus was God, doesn’t that make two Gods?” Indeed. And I am surprised Ehrman fails to mention that both the Ebonite and Nazarene sects of early Jewish Christians lodged this argument. It was Gentile Christians in the next century, such as Ignatius, who started saying Jesus is God. When they did, critics accused them of believing in two gods. But Ehrman says (p. 49) that he was enlightened to learn that “Christians were calling Jesus God” in “competition” with “the Romans calling the emperor God.” Maybe in the second century, but not the first century as Ehrman claims.
