The culture, the society and the very understanding of ourselves is NOT the same as in 1017.

And our church does not posses THE TRUTH which is God.  We don't OWN God.  Our understanding of truth has evolved over the centuries.  Maybe you still live in a cave and still run from a saber-toothed tiger.  But the rest of us live in a technological world---and that also shapes how we understand relationships with others and even with God.
