Early Christianity was a religion of mysteries. Only the initiates received all the knowledge, not the masses of believers (Paul, who believed in the second coming during his lifetime, wanted the secrets to be revealed so that more people could be saved). Furthermore, there were several Christian sects, some of them Gnostic, some who totally rejected Judaism, some who rejected Jesus' divinity, some who didn't believe Jesus was crucified by men. The passage you quoted seems Gnostic to me, but I could be wrong. Reminds me of the Gnostic story of Jesus the god who made himself human (poor), in order to descend into our world undetected by evil deities (of which the Demiurge was one) and show humans how to save their souls (immortal in a perfect world = rich). The above it's guesswork, of course, based on my rather limited knowledge. Just a sample of how a canonical text can tell us a totally different story if we look at the wider context in which it had been written.
