“The terrible error in the course of human civilization is undoubtedly the defective judgment that allowed religious authorities usurp the foundation of societal morality, in which all collective ethics of humankind must take a cause. This appalling blunder is comparable only to assigning the leper exclusive franchise to run beauty clinics in the society; this can only lead to cycles upon cycles of common infection syndrome.”

“No human race is superior; no religious faith is inferior. All collective judgments are wrong. Only racists make them”

“For society, marriage is undoubtedly beneficial. But the burdens of civilized morality are too heavy for many to bear.”

“The mysterious, invisible authority of the divine child over human hearts is more solidly grounded then the visible and resplendent power of earthly rulers. Ultimately all authority on earth must serve only the authority of Jesus Christ over humankind.”

“If religions are diseases of the human psyche, as the philosopher Grintholde asserts, then religious wars must be reckoned the resultant sores and cankers infecting the aggregate corpus of the human race. Of all wars, these are the most detestable, since they are waged for no tangible gain, but only to impose a set of arbitrary credos upon another's mind.”

“Historically, all ethics undoubtedly begin with religion; but I do not now deal with historical questions. I do not ask who was the first lawgiver. I only maintain that it is we, and we alone, who are responsible for adopting or rejecting some suggested moral laws; it is we who must distinguish between the true prophets and the false prophets. All kinds of norms have been claimed to be God-given. If you accept 'Christian' ethics of equality and toleration and freedom of conscience only because of its claim to rest upon divine authority, then you build on a weak basis; for it has been only too often claimed that inequality is willed by God, and that we must not be tolerant with unbelievers. If, however, you accept the Christian ethics not because you are commanded to do so but because of your conviction that it is the right decision to take, then it is you who have decided.”
