If Jesus was a Christian ( and the son of God ), why aren't Christian's God's chosen people then? Jews are.
There is no such thing as God's "chosen people" anymore. He had a covenant with Abraham and he'll always honor that. It gives them certain privileges and protections simply because of who their ancestor was.
But it was made very clear that "chosen" status became a thing of the past during Paul's time when he was shown that Gentiles were entitled to the Gospel as well.
I don't think you're understanding what I'm saying. Jesus was a Jew by birth, but he introduced a new spiritual archetype into the world. It was an evolution, a new design. And he was the first design. That's why an entire religion is named after him. He was the first. Everyone else tries to copy him. He was the first Christian. It doesn't mean you would call him Christ the Christian, because that's redundant, but once you understand what mindset is being described by the word "Christian", you understand that he was truly the first one.
No idea why this is even a point of contention.
