I respect your view and we have talked once, so I hope you know I am sincere.
I have to say, when you said , "something tells me that God doesn't care if it has pagan origins" IMO this could not be more wrong. I know I just posted it, but how can you say He does not care when HE SAYS THIS?
Deuteronomy 12:29-32, “When Yahweh your Father cuts off the nations from in front of you, and you displace them and live in their land, Be careful not to be ensnared into following them by asking about their gods, saying: How did these nations serve their gods? I also will do the same. You must not worship Yahweh your Father in their way, for every abomination to Yahweh, which He hates, they have done to their gods. They even burn their sons and daughters in the fire as sacrifices to their gods. Whatsoever I command you, be careful to observe and do it, you shall not add to it, nor take away from it."
must not
which He hates
