René Salm has so far compiled 26 web pages addressing Hermann Detering’s “new” argument for Christian origins involving influences from the East:
Dr. Hermann Detering
“The Gnostic Meaning of the Exodus and the Beginning of the Joshua/Jesus Cult” (2018)
Commentary by René Salm
This extensive series of posts explores literary, religious, and historical links between Buddhism and Christian origins.
It argues that Christianity emerged from a gnostic substratum,
and that the figure Jesus of Nazareth and the New Testament gospels
are second century CE developments.
I have not caught up with all of these yet but look forward to doing so.
And I see that the prolific Robert M. Price has a new book out:
Bart Ehrman interpreted : how one radical New Testament scholar understands another
I bought the kindle edition and, as usual with a RMP book, found it very easy to read. I think many would be eager to see Ehrman respond in some detail but I suspect anything from that quarter will fall short of engagement in debate.
