There's nothing wrong with nations keeping their indigenous cultures intact. Christianity was Europeanized and our own holidays reflect our indigenous cultures and holidays rather than Jesus and Yahweh. The Lord doesn't care about our trappings, if we remain Greek or German or Irish, or what our cultural rituals are, as long as we recognize Him as Lord and savior and follow His law for living. Amen and long live cultural diversity. It is the tapestry if life..
***There's nothing wrong with nations keeping their indigenous cultures intact***
I think this doesn't really fall under the heading of keeping other cultures intact. It's more like pure paganism, worhipping other gods, breaking the first commandment.
