So...do you think that Jesus of Nazareth is the Eternal Son of God who literally rose from the dead? If yes then you need to re-visit your opinions about revelation. The fundamental idea of Christianity is that God took flesh to reveal Himself to us concretely, face to face, so that we might actually know His true nature and His desires for us. This Jesus, according to revelation, also proposed adherence to Him as the only pathway to eternal salvation. If Jesus did not secure for us a way of knowing with certainty who He is and what is required of us then He is profoundly unjust as our salvation is gravely at stake because we can't be sure about what God desires from us.

If you don't then you are by definition not a Christian and you can carry on saying what you like.
