St. John of Kronstadt on sliding into atheism

"Half educated people and over-educated people do not believe in a personal, righteous, omnipotent, and unoriginate God, but believe in an impersonal origin, and in some kind of evolution of the world and all beings. Therefore they act as if they will not have to give an answer to anyone for their words and deeds, making gods of themselves, their reason, and their passions. In their blindness they reach the point of insanity, deny the very existence of God, and maintain that everything stems from blind evolution. But he who has an intellect does not believe such insane ravings."
