Anyway I thought I'd use this to show some "alternative" interpretations to the passages he uses here.
Ephesians 2:8-10 - It's basically talking about faith in the mythos of what Christ represented and it's related teachings. History was taught back then for a purpose, not as just a string of facts. If you reduce it to faith in a string of "facts" where will your faith go if evidence shows your "facts" are wrong. I actually wrote a bit more in depth about this passage and it can be found
hereBefore I begin, let me give a little background about John, it's a Gentile retelling of the Tanahk with the purpose of contrasting the Tanahk's view of tribal God, YHWH with the developing view of a Universal God promoted by Christianity.
John 3:16 - If YHVH supposedly made the world perfect, then why would it need saving? The traditional answer is because the "Fall of Man" was so great that it rocked the foundations of the universe but such an interpretation means that somehow "Man" put a kink in this god's plans. The early Christians who used this text believed the world was created flawed from the beginning and that Christ came to rescue it from itself. (Note this is before a canon was established). Symbolically, the world is one's perspective and worldview, what the Son, the image of God, is supposed to be saving is one's perspective/worldview from itself. "the Son of God" is an old expression meaning "Perfect image of God" not a literal child.
John 14:6 (foregoing the KJV translation here, it screws it up here) 6 Jesus answered, “I am the way and the truth and the life. No one comes to the Father except through me.
One finer point edit:
6 Jesus answered, “I am the way and the truth and the life. No one comes to the Father except by emulating me.
Early Christian worship is nothing like Christian worship is today. Early Christian worship was primarily emulation of the Christ mythos. There were reasons the Romans regarded the Christians as atheists besides not worshiping their Gods.
Anyway here's how I take this passage, "Mythically, Christ is the perfect image of what this Universal God would be like if he were a man, if you want to better know this God, then emulate Christ and trust his teachings."
John 3:36, this is a dualistic passage contrasting YHVH and Yeshua's God. Translation: Follow image of God and you'll get to know the universal God, don't and you'll stay under the wrath of YHVH. It's a stab saying that the Judeans were getting it wrong.
Anyway that's my two cents.
