My impression of Luther is his being extremely religious to the point of superstition, overwhelmed with a fear of Satan that manifested itself by verbal outbursts. He despised his human condition and referred to himself as a foul bag of maggots.
Luther took humbling himself before God beyond reason by diminishing himself as much as exalting God.
He was his own worst critic, which goes in train with being brutally honest. A rarity in his circle. If there is such a thing, Luther was a religious existentialist, fearless in going to battle against his human condition, which at bottom verged on self-flagellating masochism.
He began to hold the Church to the same honest rigor as he possessed, which led him inevitably to criticizing that which he could not change. His self-inegrity allowed of nothing else.
Well, it's hard to throw off a lifetime of Catholic indoctrination and mindset all at once.
I just HATE it when things like that are exposed!!
