The faith a movement proclaims doesn't count: what counts is the hope it offers. All heresies are the banner of a reality, an exclusion. Scratch the heresy and you will find the leper. Every battle against heresy wants only this: to keep the leper as he is.

At any given moment there is an orthodoxy, a body of ideas of which it is assumed that all right-thinking people will accept without question. It is not exactly forbidden to say this, that or the other, but it is “not done” to say it… Anyone who challenges the prevailing orthodoxy finds himself silenced with surprising effectiveness. A genuinely unfashionable opinion is almost never given a fair hearing, either in the popular press or in the high-brow periodicals.

<i>Two contrary reasons</i>. We must begin with that, otherwise we cannot understand anything and everything is heretical. And even at the end of each truth we must add that we are bearing the opposite truth in mind.

I did try to found a little heresy of my own; and when I had put the last touches to it, I discovered that it was orthodoxy.

Canonical books. The heretics at the beginning of the Church serve to prove the canonical books.

It has been said that heresy is the revenge of a forgotten truth.

Heresy is the life of a mythology and orthodoxy is the death.

"Some religions actually go so far as to label anyone who belongs to a religious sect other than their own a heretic, even though the overall doctrines and impressions of godliness are nearly the same. For example: The Catholics believe the Protestants are doomed to Hell simply because they do not belong to the Catholic Church. In the same way, many splinter groups of the Christian faith, such as the evangelical or revivalist churches, believe the Catholics worship graven images. (Christ is depicted in the image that is most physiologically akin to the individual worshipping him, and yet the Christians criticize "heathens" for the worship of graven images.) And the Jews have always been given the Devil's name."

Heretics must believe. More than anyone else in an organization, it's the person who's challenging the status quo, the one who is daring to be great, who is truly present and not just punching a clock who must have confidence in her beliefs.
Can you imagine Steve Jobs showing up for the paycheck? It's nice to get paid. It's essential to believe.

The power of organized religions is based upon their contribution to social order and personal security, not to the search for truth. The goal of religions is submission to the will and common good of the tribe. The illogic of religions is not a weakness in them, but their essential strength. Acceptance of the bizarre creation myths binds the members together.

When an angry mob demands the death of a female English schoolteacher alleged to have insulted the Prophet, as happened in Sudan in November 2007, the real objective was not the defence of Islam but of honour, which – it was felt – had been slighted for many long years by the Western powers. This ‘spontaneous’ use of religion was accompanied by its deliberate instrumentalization by those who are pursuing other objectives, but who prefer this disguise. Even the Crusades, as I have said, had several motives other than religious ones, but these motives were merely less easy to admit to; so they preferred to declare that Jerusalem needed to be liberated. Such a cause appears nobler; and, in addition, the appeal to cultural identity allows more powerful inner resources to be mobilized.

In the end the Party would announce that two and two made five, and you would have to believe it. It was inevitable that they should make that claim sooner or later: the logic of their position demanded it. Not merely the validity of experience, but the very existence of external reality, was tacitly denied by their philosophy. The heresy of heresies was common sense. And what was terrifying was not that they would kill you for thinking otherwise, but that they might be right. For, after all, how do we know that two and two make four? Or that the force of gravity works? Or that the past is unchangeable? If both the past and the external world exist only in the mind, and if the mind itself is controllable — what then?

That there must be heresies is true, not onely in our Church, but also in any other; even in Doctrines hereticall there will be super-heresies, and Arians not onely divided from their Church, but also among themselves: for heads that are disposed unto Schisme...are naturally indisposed for a community, nor will ever be confined unto the order or oeconomy of one body; and therefore when they separate from others they knit but loosely among themselves; nor contented with a general breach or dichotomie with their Church, do subdivide and mince themselves almost into Atomes.
