Scratch the heresy and you will find the leper. Every battle against heresy wants only this: to keep the leper as he is.

But why do some people support [the heretics]? Because it serves their purposes, which concern the faith rarely, and more often the conquest of power. Is that why the church of Rome accuses all its adversaries of heresy? That is why, and that is also why it recognizes as orthodoxy any heresy it can bring back under its own control or must accept because the heresy has become too strong.

I may err but I am not a heretic, for the first has to do with the mind and the second with the will!

The malice of a true Christian attempting to destroy an opponent is something unique in the world. No other religion ever considered it necessary to destroy others because they did not share the same beliefs. At worst, another man's belief might inspire amusement or contempt— the Egyptians and their animal gods, for instance. Yet those who worshipped the Bull did not try to murder those who worshipped the Snake, or to convert them by force from Snake to Bull. No evil ever entered the world quite so vividly or on such a vast scale as Christianity did.

I say that many of these heresies, independently of the doctrines they assert, encounter success among the simple because they suggest to such people the possibility of a different life. I say that very often the simple do not know much about doctrine. I say that often hordes of simple people have confused Catharist preaching with that of the Patarines, and these together with that of the Spirituals. The life of the simple, Abo, is not illuminated by learning and by the lively sense of distinctions that makes us wise. And it is haunted by illness and poverty, tongue-tied by ignorance. Joining a heretical group, for many of them, is often only another way of shouting their own despair. You may burn a cardinal's house because you want to perfect the life of the clergy, but also because you believe that the hell he preaches does not exist.

Even a child could see the division between what the Galileans [i.e., Christians] say they believe and what, in fact, they do believe, as demonstrated by their actions. A religion of brotherhood and mildness which daily murders those who disagree with its doctrines can only be thought hypocrite, or worse.

Progress is born of doubt and inquiry. The Church never doubts, never inquires. To doubt is heresy, to inquire is to admit that you do not know— the Church does neither.

There is obviously something wrong with our educational system. It is not beyond the realm of possibility that there might even be something wrong with at least some of our schoolteachers. But heaven help anyone daring to express such heretical views.

One century's saint is the next century's heretic ... and one century's heretic is the next century's saint. It is as well to think long and calmly before affixing either name to any man.

All right, so you believe in Santa Claus, and I'll believe in the 'Great Pumpkin.' The way I see it, it doesn't matter what you believe just so you're sincere! (Linus)

The Devil answer'd: bray a fool in a morter with wheat, yet shall not his folly be beaten out of him; if Jesus Christ is the greatest man, you ought to love him in the greatest degree; now hear how he has given his sanction to the law of ten commandments: did he not mock at the sabbath, and so mock the sabbaths God? murder those who were murder'd because of him? turn away the law from the woman taken in adultery? steal the labor of others to support him? bear false witness when he omitted making a defense before Pilate? covet when he pray'd for his disciples, and when he bid them shake off the dust of their feet against such as refused to lodge them? I tell you, no virtue can exist without breaking these ten commandments; Jesus was all virtue, and acted from impulse, not from rules.

The religious geniuses of all ages have been distinguished by this kind of religious feeling, which knows no dogma and no God conceived in man's image; so that there can be no church whose central teachings are based on it. Hence it is precisely among the heretics of every age that we find men who were filled with this highest kind of religious feeling and were in many cases regarded by their contemporaries as atheists, sometimes also as saints. Looked at in this light, men like Democritus, Francis of Assisi, and Spinoza are closely akin to one another.

Perchance you who pronounce my sentence are in greater fear than I who receive it.

Sin, blasphemy, heresy – all these are primitive ideas created by primitive creatures, unworthy of the title —human—.
