In How Jesus Became God author Bart Ehrman explains that the historical Jesus was an apocalyptic preacher who went about a small rural area portraying himself as a prophet. He prophesied the end was near. God would intervene in human affairs, throw out the forces of evil and set up a Godly kingdom here on earth.
There is enough surviving written material for scholars to conclude there were many other preachers walking about with this same apocalyptic message to Jews of that day. Jesus was but one of the many.
Ehrman gives talks and debates in both conservative and liberal Christian venues. At conservative ones, he says, the audiences are polite. There is often a debate with a local scholar who is a believer. Those audiences are not that interested in what Ehrman has to say but in how their local professor does in the debate.
At liberal places he says audiences are more interested in his historical information about the time of Jesus. When they learn about the apocalyptic Jesus and the many other end of times messagers they ask, “Why have we not heard of this?” Ehrman explains that main line seminaries, Presbyterian, Lutheran, Methodist, Episcopalian, etc. all teach this history. Mostly, however, their graduate preachers do not present it in sermons.
Ehrman says he has asked pastors why they do not discuss this history. The frequent answer is preachers do not want to upset the faithful.
I’ve said before, sermons are written by those in the pews.
