There was a post on this thread where a writer spoke of two pillars one being te bible and how over the last 60 years that it has come under pitched assault -- (from leftist self-styled intelectuals -- my words) and that has eroded the pillar of the word of God in the eyes of the generations that have grown up during that era.
In the 1970's I remember well the assualt on the bible there were two different moses' the J writer and another writer and two Isaiah's the first wrote some and the latter added info centuries later that made the man appear to phrophesy. I heard it then and again three days ago that we could not be made in God's image of likeness, because He is some kind of gas. I have hear it said back then that when the bible says: Gods arm or God's hand that is only figurative -- because gas has no hand or arm. The word they used for all taht was anthropormorphism: that is that God was only pretending to be like us so that we might relate with him. (Seems to be calling Him a Liar, these people have no faith, and don't beleive in miracles.)
My point is a bit rambling but I see these other people as products of that sustained attack on the bible. They have been poisoned, and injured, and afraid to look at the Bible because they have lost faith in it and no longer know what to beleive whereas they know that they are on "solid ground" in the Catechism.
