Yes you can be a Pagan Christian, Hawaiian Christian, etc., etc.,
If you know the Gods and Goddesses names and their stories. The stories of your homeland. The stories of your culture. That does not make you a sinner it does not send you directly to hell. Some lessons from your people’s past are not in the Jesus book. How will you know if your leaders are lying to you about what God says if you do not know what your ancestors said before them. The old ones, the ancients, the church of the opposition that came before the current religion.
