Keep in mind that Christianity is more than just the Bible. Catholics, for example, were around before the New Testament was ever written.
Uh, no. The "new testament" is actually the Gospel of Christ, the inspired word as written by the apostles. It's the foundation of the early church(s) Pauls, Peters, John etc. They were the first "Catholics" Or at least Peter was, since Catholics are all extentions of Peter's Church.
Later, these books were canonized to form what we now call the new testement.
And no, Jesus doesn't have a penis. No flesh shall enter heaven remember. Read Revelations as well. Sheesh.
Absolutely true. Christians existed for centuries before the NT canon was settled in 382 AD.
