You may see it this way, but consider this: Christianity existed amongst the denizens of pre Traveller Earth. We have point C on Widow's court inside a church for example. Then the Traveller came. I don't know if you've noticed, but the Tower citizens worship the Traveller - not Jesus. The Traveller [b]overthrew[/b] Earthly religions. The Speaker is the High Priest of the Traveller. We each carry a Ghost, born of the Traveller, who resurrects us, literally, every time we die. Jesus said "I am the way, the truth and the light, the only way to eternal life is through me", but it turns out that the Destiny universe that has been proved incorrect. In the Destiny universe the only way to eternal life is through the Traveller. I would argue that Destiny is specifically oppositional to Christianity, and that the parallels that you see are there not to make the story allegorical, but to show that the Traveller has power that we traditionally associate with Godhood.
