I agree with your second statement; but, I (not being a Bible scholar) have no knowledge of a scriptural ban on cremation. Can you help me with that?
Again, look up at the defense for cremation a bit higher up in the thread.
“The spirit is everything. The body is nothing”. This is contrary to what Paul teaches. The body is important. If the body will be resurrected, then we have a duty to preserve the body. If the body is nothing, then cremate away.
