Christianity differs from Buddhism in its history, stories, characters, practices, teachings, texts, monotheism, non-cyclical life, and the specific factions and communities, which do almost all inherit much from Catholicism, including very heavy emphasis (even definition) on Jesus’ resurrection and what it means. The Christian religion and communities do tend to be very focused on saying their idols and doctrines are the right ones, and that one’s immortal soul is in danger and that accepting Jesus is the path to salvation, etc. That’s the religion, but the original spiritual intent is a different thing.
I feel that the core spiritual intent of almost every spiritual tradition (and thus the religions built on them) is basically the same, and involves transcending earthly ego concerns and becoming enlightened and one with the world, and so at peace, and able to peacefully let go of our attachment even to our life and peacefully accept whatever comes, even death and what may come after. The specific stories and teachings are just the details of means to an end.
(By the way, the historical Jesus was an educated man who grew up in a trade city on the spice road and so was exposed to various spiritual traditions including Buddhism.)
As for religion, it is not needed for a spiritual life, and it may get in the way, particularly for an educated modern Westerner surrounded by so many dysfunctional, tragic and conflicting religious messages. I may be wrong, but I don’t think Jesus would have said he was religious, in the sense I mean it. That is, not belonging to an organized social group with idolized writings and idols and physical artifacts and ranks and doctrines and so on. They can be useful tools, but they can also get in the way. Many of the most spiritually hard-core early Christians would go live in the wilderness (deserts, mountains, caves) to avoid distractions from their spiritual paths, which is basically like being a yogi in other traditions.
“Finding divinity in yourself” is a realization that can come when you for example shed your ego identity and attachments, identify as being an inseparable part of the universe, and realize that includes being a part of the cause of things and the invention of meanings, that you’re not a separate creature struggling against the plight of being one beast in a harsh universe, but that you’re part of creation, and whatever happens is ok and other insights that bring a lot of peace and possibility. Jesus demonstrated this as an example to follow in his surrender to crucifixion and his ascension. Again, it’s a good example of a parable to shake up our thinking and not a suggestion to go get martyred. But that is the actual original metaphorical meaning of the crucifixion – and certainly not to treat him as an idol and object of worship, or to think of ourselves as bad and in need of proclaiming our belief that he gave himself to redeem us and that we are therefore “saved” from eternal torment in hell. No way! The point was that we are all bigger than that and don’t need to fear death if we get his example. Jesus didn’t “take the fall to buy us a pass if we believe.” Original Sin is a metaphor for the mistake of getting wrapped up in our lives and material attachments, and if we don’t follow his example of tuning out of that, our souls will suffer all right, but because we get stuck in a self-tormenting frame of mind worried about our mortality and credit card debts and so on.
