Native drumming is no better than hard rock. Native Americans were involved in sinful practices long before the white man came along, as was the white man before coming to America. The newsletter complains that missionaries to Native Americans made the mistake of calling the latter's culture pagan and trying to get them to adopt the white man's culture. It is essential, however, to abandon paganism. Thus the newsletter admits that Native culture is inextricably linked with native religion.
Native religion is pagan and it permeates native culture.
Clearly, then, the pagan elements in the culture must be abandoned if one is to come to Christ. Abraham was called out of paganism. The Old Testament makes a clear distinction between the paganism of the nations surrounding them and the holiness to which Israel was called. Israel was condemned for trying to mix its God-given worship with the idolatry of its neighbors. There is never a suggestion that Christianity was to adapt itself to any pagan culture, as the quoted newsletter demands by way of special respect for Native Americans.
