“He that has doctrinal knowledge and speculation only, without affection, never is engaged in the business of religion.”

“Science is a way to call the bluff of those who only pretend to knowledge. It is a bulwark against mysticism, against superstition, against religion misapplied to where it has no business being.”

“But it is common knowledge that religions don’t want conviction, on the basis of reasons, but faith, on the basis of revelation. And the capacity for faith is at its strongest in childhood: which is why religions apply themselves before all else to getting these tender years into their possession. It is in this way, even more than by threats and stories of miracles, that the doctrines of faith strike roots: for if, in earliest childhood, a man has certain principles and doctrines repeatedly recited to him with abnormal solemnity and with an air of supreme earnestness such as he has never before beheld, and at the same time the possibility of doubt is never so much as touched on, or if it is only in order to describe it as the first step towards eternal perdition, then the impression produced will be so profound that in almost every case the man will be almost incapable of doubting this doctrine as of doubting his own existence, so that hardly one in a thousand will then possess the firmness of mind seriously and honestly to ask himself: is this true?”

“But yet it is evident that religion consists so much in affection, as that without holy affection there is no true religion; and no light in the understanding is good which does not produce holy affection in the heart: no habit or principle in the heart is good which has no such exercise; and no external fruit is good which does not proceed from such exercises.”

“It is bad religion to deify doctrines and creeds.... Doctrines, let's not forget, supported slavery and apartheid.... Moreover, doctrines can divide while compassion can only unite.”

“It is impossible for there to be a person with no religion (i.e. without any kind of relationship to the world) as it is for there to be a person without a heart. He may not know that he has a religion, just as a person may not know that he has a heart, but it is no more possible for a person to exist without a religion than without a heart.”
