If Jesus physically came back today would Christians actually accept him?

I got the idea for this question from something similar asked by rebbel. If Jesus actually really came back today as he was 2000 years ago but told most Christians that their religious beliefs from the bible was was not his true message do you think mainstream Evangelicals/or fundamentalists would actually accept him or claim he is a false or antichrist? What if Jesus/Yeshua’s message today was to accept everyone regardless of their sexual orientation, lifestyles, religious beliefs, etc.? What if his message was heaven through works, not faith? What if another of messages was that the term “hell” is really a state people put themselves in and not an eternal place of punishment? What if Yeshua told Christians that his message has been distorted by the men writing the bible to push their own religious/political agenda? What if Yeshua’s true message was that of secular humanism? This is a theoretical question, assuming Yeshua really existed and really was god incarnated as human. I don’t want any arguments of whether Jesus/Yeshua actually existed or if he was god or not. Its just a hypothetical question on how you would think many mainstream Christians would respond to such an entity. Atheists/agnostics are welcome as long as they stay on topic. I will admit it may take some biblical knowledge as well as spiritual knowledge to fully understand my question here.
