Here is a counter-cultural quote from a Lutheran theologian (the name mentioned in the quote has been removed to increase the difficulty factor). So, who said it?
"We should stop stabbing at pietism. It is always misunderstood, so that one would think that we disdain conversion and lack a sense of the factor of personal responsibility in Christianity.... Personally, I am convinced that the portion of pietism, which is found in *****, is useful for salvation, not to mention necessary."
