It seems to me that this is a fundamental watershed between evangelicals. Those of us in the Pietist tradition claim unmediated experience of God that authenticates scripture to us but makes it impossible to see scripture as proving that God is evil or the author of sin and evil or loves his own glory more than he loves people created in his own image and likeness. Those evangelicals in the Protestant scholastic tradition at least claim to experience God only through scripture and at least say they would believe the Bible even if it said God is a monster, the author of sin and evil, who loves his own glory to the extent that it causes him to hate some of the creatures created in his own image and likeness.
I hope that whets your appetite for the whole post, which I think is very good. Far too many Christians view the Trinity as Father, Son, and Holy Bible. That is what Roger is pushing back against—rightly so.
