Quote from : Under the Unpredictable Plant an Exploration in Vocational Holiness Book

Deception is nowhere more common than in religion. And the persons most easily and damningly deceived are the leaders. Those who deceive others are first themselves deceived, for not many, I think, begin with evil intent. The devil, after all, is a spiritual being. His usual mode of temptation is not an obvious evil but to an apparent good. The commonest forms of devil-inspired worship do not take place furtively at black masses with decapitated cats but flourish under the bright lights of acclaim and glory, in a swirl of organ music.
