In the comment section of another blog, the following was said:
But the question is, if there were ever undeniable “proof” that Jesus was not physically resurrected and the early Christians didn’t truly believe he was then would you still be able to be a Christian. You seem to be saying no, others would say yes. Now as I’ve pointed out in the previous blog that Denny posted that I linked to, the difference between you and these other types of people is that you probably would never even consider the “proof” of whether Jesus was physically resurrected or not. You would in a sense cover your eyes and plug your ears, whereas the other type would be willing to consider the proof and possibly even agree with it. But instead of abandoning their faith they would instead just reorient their beliefs.
How in the world do people say stuff like this and expect to be taken seriously? Unfortunately, this is the type of stuff that passes for serious thought these days.
Fortunately, it is the type of stuff that God directly spoke about in 1 Corinthians 15. He said that if the resurrection of Jesus did not actually happen, then our faith is vain.
So yes, if the resurrection of Jesus did not actually happen, then we would need to seriously reorient our beliefs. But we certainly would not still be able to be a Christian.
