Not really. There are nondualist traditions within Christianity. Meister Eckhart being the most well known. Nonduality isn’t the worshipping of other gods before Yahweh, it’s the belief that all that exists is within God. Panentheism isn’t incompatible with Christianity, it’s just a super niche trend within it, but with lots of historical precedent, even within large Christian organizations like the RCC. They never excommunicated Eckhart, and while he was controversial during his life, his thoughts on nonduality effectively forced the church to admit that it was not heresy.
Going beyond the RCC and into protestantism there is no unifying body to declare what is and isn’t allowed, so basically, screw that, imma do what I want.
But if you’re at all interested (not in a “Join us!” Way, more in an interesting historical knowledge way), there are tons of nondualist Christians, and I’d be happy to share.
