In this 3-minute video, watch John Shelby Spong deny the existence of Hell, dismiss sin, decry being born again, assert that religion is about control, set aside the Bible, and other such things.
He doesn't cite his authority or sources for these truths. How does he back this up? Are we to take his word for it? Why should I believe in the gospel according to John Shelby Spong as opposed to the gospel according to the Bible?
