Welcome GAMEGIRL.
I'm sure you will be loving and gentle with your dad if ever discussing the Org's version of the Bible with him. On here, you will come to learn things which you feel your father must learn, but don't beat him over the head with them. Simply ask him questions about a given subject, and get him to analyze WHY he believes what he does, compared with what certain Scriptures say.
That way, you could help him to see what the Bible REALLY teaches!
