Reason is the greatest enemy that faith has: it never comes to the aid of spiritual things, but--more frequently than not--struggles against the divine Word, treating with contempt all that emanates from God.

Philosophy and religion are enemies, and because they are enemies they have need of one another. There is no religion without some philosophical basis, no philosophy without roots in religion. … the attacks which are directed against religion from a presumed scientific or philosophical point of view are merely attacks from another but opposing religious point of view.

It is time we recognized that all reasonable men and women have a common enemy. It is an enemy so near to us, and so deceptive, that we keep its counsel even as it threatens to destroy the very possibility of human happiness. Our enemy is nothing other than faith itself.

en fait de religion, les plus proches sont les plus grandes ennemies.

The most deadly enemies of the Roman Catholics are they who love best their religion as Protestants. When we look to individuals we always find it so, though it hardly suits us to admit as much when we discuss these subjects broadly.

Jesus Christ reigns here over the minds of his servants by faith, and over their hearts by charity. The greatest enemies of his spiritual kingdom are errors and vices, heresies, schisms, and scandals. Christ himself has foretold that his Church on Earth should have such enemies to encounter. She is not here below in the place of her repose, but in a place of trial, and in a foreign country. She must of course necessarily expect to meet with severe trials and persecutions, and must be prepared to combat them.

It is not only the prohibition against criticizing the Quran and the Prophet that closes the Muslim mind, and not only the life-long socialization of learning by rote. It is also the continuous construction of conspiracy theories about enemies of Islam who are determined to destroy the one, true religion.
The chief enemy is the Jew.

Whatever its imagined virtues, faith is the enemy of open and honest inquiry. Remaining open to the powers of conversation - to new evidence and better arguments - is not only essential for rationality. It is essential for love.

Our Government and our Laws are beset by two different Enemies, which are sapping its foundations, Indianism, and Jacobinism. In some Cases they act separately, in some they act in conjunction: But of this I am sure; that the first is the worst by far, and the hardest to deal with; and for this amongst other reasons, that it weakens discredits, and ruins that force, which ought to be employd with the greatest Credit and Energy against the other; and that it furnishes Jacobinism with its strongest arms against all formal Government.

There are two religions in earth, which have distinct enmity against all other religions. These two are Christianity and Islam. They are not just satisfied with observing their own religions, but are determined to destroy all other religions. That’s why the only way to make peace with them is to embrace their religions.”

[Religion] is predominantly evil and entirely deceitful, has only negative correlations statistically, and is frequently maliciously abusive physically mentally and emotionally. It has historically always obstructed education and retarded or impeded progress in whatever application it has ever touched. All the worst atrocities in history were done in the name of religion and our greatest advances were made in opposition to it. I’m an antitheist because religion is factually historically ethically and morally wrong.

As is well known, the priests are the most evil enemies — but why? Because they are the most impotent. It is because of their impotence that in them hatred grows to monstrous and uncanny proportions, to the most spiritual and poisonous kind of hatred. The truly great haters in the world history have always been priests; likewise the most ingenious haters: other kinds of spirit hardly come into consideration when compared with the spirit of priestly vengefulness.

Common to all these enemies is that none of them accepts the reality of the "whole system": we do not exist in such a system. Furthermore, in the case of morality, religion, and aesthetics, at least a part of our reality reality as human is not "in" any system, and yet it plays a central role in our lives. To me these enemies provide a powerful way of learning about the systems approach, precisely because they enable the rational mind to step outside itself and to observe itself (from the vantage point of the enemies).

This country desperately needs a God-centered president, senators and congressmen. America's intellectual establishment is liberal, godless, secular, humanistic, and anti-religious. We are declaring war against three main enemies: godless communism, Christ-less American liberalism, and secular-humanistic morality. They are the enemies of God, the True Parents, the Unification Church, all of Christianity, and all religions. We are working to mobilize a united front against them.
