In which denomination(s) are Christians allowed to bury or hold a Christian funeral for their deceased nonreligious or just non-Christian relative in a Christian cemetery near the church? I am thinking about an instance where a non-Christian or nonreligious family member dies, and relatives just happen to be Christians. Do Christians ask their minister to perform a funeral for the deceased individual, or do they ask a humanist funeral officiant to do the job? Also, is there a general rule for allowing or disallowing non-Christians to be buried in a Christian cemetery, or is that more of a denominational sort of thing or is that up to the pastor to decide?
