It is necessary, therefore, to prove clearly that in the Early Church, at least, Christianity was no whit behind other great religions in possessing a hidden side, and that it guarded, as a priceless treasure, the secrets revealed only to a select few in its Mysteries. But ere doing this it will be well to consider the whole question of this hidden side of religions, and to see why such a side must exist if a religion is to be strong and stable; for thus its existence in Christianity will appear as a foregone conclusion, and the references to it in the writings of the Christian Fathers will appear simple and natural instead of surprising and unintelligible. As a historical fact, the existence of this esotericism is demonstrable; but it may also be shown that intellectually it is a necessity.

Are not all religions strange to those who stand outside of them?

Outside Christianity humanity can doubtless be raised in an exceptional manner to certain spiritual heights, and it is our duty—one that is perhaps too often neglected—to explore these heights that we may give praise to the God of mercies for them: Christian pity for unbelievers, which is never the fruit of scorn, can sometimes be born of admiration. But the topmost summit is never reached, and there is risk of being the further off from it by mistaking for it some other outlying peak. This is a fact noticed by many missionaries. It is often more difficult—though in the last resort more worthwhile—to bring to the fullness of truth souls whom a relatively more developed religion has stamped with its mark. A critical judgement, not of individual souls—for their precise situation in relation to the Kingdom is never known save to God alone—but of objective systems as found in a society and as offering material for rational examination, shows that there is some essential factor missing from every religious "invention" that is not a following of Christ.[…] Outside Christianity all is not necessarily corrupt; far from it,[…] but what does not remain puerile is always in danger of going astray, or, however high it climbs, of ultimate collapse. Outside Christianity nothing attains its end, that only end, towards which, unknowingly, all human desires, all human endeavours, are in movement: the embrace of God in Christ.

The distinction between Christianity and all other systems of religion consists largely in this, that in these other, men are found seeking after God, while Christianity is God seeking after man.

Many, perhaps most, who see the title of this book will at once traverse it, and will deny that there is anything valuable which can be rightly described as "Esoteric Christianity." There is a wide-spread, and withal a popular, idea that there is no such thing as an occult teaching in connection with Christianity, and that "The Mysteries," whether Lesser or Greater, were a purely Pagan institution. The very name of "The Mysteries of Jesus," so familiar in the ears of the Christians of the first centuries, would come with a shock of surprise on those of their modern successors, and, if spoken as denoting a special and definite institution in the Early Church, would cause a smile of incredulity.

Christianity may be true or false, but it makes claims subversive of all the rationalist projections of life. It rests on presuppositions which cannot by any ingenuity be reconciled with any view which denies the miraculous, the unique, the individual. Its whole meaning comes from a faith in a life of spirits behind the veil. It cannot without hopeless error be confused with those systems which deny such a life or treat it as impersonal.

All religions worthy of the name are now making great efforts to purify their doctrines and return to their original standpoint, all except Christianity! You surely know that the nineteenth century Christianity is not the religion taught by Christ. Christ's religion has been changed and corrupted.

Christianity is not a highly complicated collection of so many dogmas that it is impossible for anyone to know them all; it is not something exclusively for academicians who can study these things, but it is something simple: God exists and God is close in Jesus Christ.

Christianity, by those doctrinal aspects that we have just emphasized as well as by others, brought something absolutely new into the world. Its concept of salvation is not merely novel in comparison with that of those religions in existence at the time of its birth. It is a unique phenomenon in the religious history of mankind.<p>For what do we witness outside Christianity whenever a religious movement rises above the domain of sense and effectively transcends the limit of nationality? In every case, though appearances may differ considerably, the basis is the same—an individualist doctrine of escape. It was this that inspired ancient mysticism, whether it sought to escape the vicissitudes of the sub-lunary world or to pass over the outer circle of the cosmos and to penetrate into the realm of intelligible Essences or even beyond.

There are the great religions beside Christianity, Hinduism, Buddhism, Islam and the remnants of classical Judaism; they have their myths and their rites — so to speak their "circumcision" — which gives each of them their distinction. There are the secular movements: Fascism and Communism, Secular Humanism, and Ethical Idealism. They try to avoid myths and rites; they represent, so to speak, uncircumcision. Nevertheless, they also claim ultimate truth and demand complete devotion. How shall Christianity face them? Shall Christianity tell them: Come to us, we are a better religion, our kind of circumcision or uncircumcision is higher than yours? Shall we praise Christianity, our way of life, the religious as well as the secular? Shall we make of the Christian message a success story, and tell them, like advertisers: try it with us, and you will see how important Christianity is for everybody? Some missionaries and some ministers and some Christian laymen use these methods. They show a total misunderstanding of Christianity. The apostle who was a missionary and a minister and a layman all at once says something different. He says: No particular religion matters, neither ours nor yours. But I want to tell you that something has happened that matters, something that judges you and me, your religion and my religion. A New Creation has occurred, a New Being has appeared; and we are all asked to participate in it. And so we should say to the pagans and Jews wherever we meet them: Don’t compare your religion and our religion, your rites and our rites, your prophets and our prophets, your priests and our priests, the pious amongst you, and the pious amongst us. All this is of no avail! And above all don’t think that we want to convert you to English or American Christianity, to the religion of the Western World. We do not want to convert you to us, not even to the best of us. This would be of no avail. We want only to show you something we have seen and to tell you something we have heard: That in the midst of the old creation there is a New Creation, and that this New Creation is manifest in Jesus who is called the Christ.

Reality, in fact, is usually something you could not have guessed. That is one of the reasons I believe Christianity. It is a religion you could not have guessed. If it offered us just the kind of universe we had always expected, I should feel we were making it up. But, in fact, it is not the sort of thing anyone would have made up. It has just that queer twist about it that real things have. So let us leave behind all these boys' philosophies — these over simple answers. The problem is not simple and the answer is not going to be simple either.

Athirst for personal salvation, the West forgets that many religions had but a vague notion of the life beyond the grave; true, all great religions stake a claim on eternity, but not necessarily on man's eternal life.

There are no special attributes to distinguish Christianity from any other collection of baseless lies. If there were no Christians tomorrow, we’d still have Muslims and a slough of other indefensible belief systems.

There are serious mistakes, among them the one saying that Jesus came as a messenger for other people other than the sons of Israel.… Christianity is not a faith for people in Africa, Asia, Europe and the Americas. Other people who are not sons of Israel have nothing to do with that religion.… It is a mistake that another religion exists alongside Islam. There is only one religion which is Islam after Mohammed.… All those believers who do not follow Islam are losers.
