Of course, Bill’s not the first to argue this, nor will he likely be the last. If there was ever a case of “moving the goalposts,” it’s here. The idea that Christianity isn’t a religion is just absurd. And yeah, you don’t have to believe Jesus is God to believe in his teachings, but as Jon Stewart rightly points out, you do have to believe that to be a Christian. At the very least, you have to believe he was raised from the dead, since it is a Cardinal Doctrine of the Christian faith.
[I]f Christ be not raised, your faith is vain; ye are yet in your sins. -1 Corinthians 15:17
Furthermore, believing only in Jesus’ teachings is nice, but according to Jesus himself, that wasn’t what was most important. In fact, Jesus says you can go against his teachings if you want and he’ll still forgive you. But if you don’t believe in him as God, then you’re in big trouble.
Wherefore I say unto you, All manner of sin and blasphemy shall be forgiven unto men: but the blasphemy against the Holy Ghost shall not be forgiven unto men. And whosoever speaketh a word against the Son of man, it shall be forgiven him: but whosoever speaketh against the Holy Ghost, it shall not be forgiven him, neither in this world, neither in the world to come. –Matthew 12:31-32
Verily I say unto you, All sins shall be forgiven unto the sons of men, and blasphemies wherewith soever they shall blaspheme: But he that shall blaspheme against the Holy Ghost hath never forgiveness, but is in danger of eternal damnation. –Mark 3:28-29
And whosoever shall speak a word against the Son of man, it shall be forgiven him: but unto him that blasphemeth against the Holy Ghost it shall not be forgiven. –Luke 12:10
Jesus essentially says the exact opposite of Bill’s “philosophic” beliefs. Listening to some of Bill's other claims in the past, I've often wondered if he's ever read an actual science book. Now I'm wondering if he's even read the Bible. So yeah, Christianity is still a religion. And incidentally, it’s also still completely wrong.
