Hmmm I've been thinking on this thread and how can we ignore the definition of apostate in the hebrew scriptures? Stan conroy makes the same point. early christians as did Jesus clearly used the hebrew scriptures as a source of direction even they felt they were no longer under certain requirements of the law.
Does the greek scriptures replace the hebrew scriptures as to make them obsolete? For giliead point to work Jws are wrong for going to hebrew scriptures for a definition of apostasy which isn't a proved point biblically.
