If Jesus was indeed God, as He claimed to be, given that he talked of and interacted with both the Devil and demons it would be folly to reject their realities.
I don’t knock Christianity because I think it led directly to the founding of the United States, which could not have happened, and will not be able to continue without it.
More power to the purity of Christian faith, by whatever demonation.
In that sense Jesus was moshiach. Though moshiach is not a concept of divinity.
I believe Jesus to have been a fine rabbi, though not divine for myriad reasons, one of which is that the Devil undermines monotheism. There cannot be One God for goodness and another for Evil. Whatever one wants to call it does not change that polytheistic effect.
If someone could point to one example of this so-called Devil, or Evil being at large in Creation before Man came on the scene, I’d be all ears and eyes. But unless some similar concept has been experienced by intelligent beings elsewhere in the cosmos...I’d yet be inclined to think it invented too, thus to pass off their own malfeasence on some agent other than themselves.
