Except that, as shown (Post 232), Abraham is called "the rock." When you're trying to make the case for exclusivity, all it takes is one counter-example to rebut that point.
God being often referred to as "Rock" doesn't preclude Peter from termed that.
I'd commend your diligent efforts, except that looks like one long copy and paste of an image taken from elsewhere.
And this somehow negates it's impact?
