Their cunning is colossal: even today, wherever they can, they will attack the core of the Gospel, if not directly, then thru sniping. Here is a recent example I just ran across:
Luther for one admitted that it was very difficult for him to achieve peace of mind on the basis of his sola fides principle, which landed him in a state of schizophrenia.
Is the "schizophrenia" here referring to Luther's famous dictum, "Simul justus et peccator"? I have not read the passage the writer is alluding to; until I actually see it, complete with its context, I will hardly be inclined to think of Luther as a mental case. Temperamental? Yes. Intense? Indisuputably. Hothead? Of course. But mentally disturbed, never.
This kind of branding reeks of the Soviet practice of committing Christians to mental institutions.
