Perhaps you are the one who needs to read more before you opine. there was nothing in any of my comments that suggested that the Old Testament was fiction. The Old Testament tells us about The Law. The Nazarene fulfilled The Law. Like paul, I am no longer bound by it. All things are lawful is completely Pauline and New Testament. Not all things are useful.
So the OT is now, not only immoral, but not useful either? While not BOUND by it, it is still the Word of God and is supremely useful, as well as moral.
