Just recently, Justin Bass posted a two part review of his recent debate with Bart Ehrman on Justin Bass vs Bart Ehrman | “Did the Historical Jesus Claim to Be Divine?
In his review he says that Ehrman says: “In none of those passages (from the Synoptics) does Jesus say ‘I am God.’”
Obviously, you can go on to read what Bass says in response to this topic. I have found this objection to come up quite a bit in my own discussions with Jewish people, Muslims, and skeptics as well. If interested, given the culture Jesus was ministering in, this is my own response as to why Jesus would never explicitly say “I am God.”
