In critically judging of the value of religious phenomena, it is very important to insist on the distinction between religion as an individual personal function, and religion as an institutional, corporate, or tribal product. I drew this distinction, you may remember, in my second lecture. The word “religion,” as ordinarily used, is equivocal. A survey of history shows us that, as a rule, religious geniuses attract disciples, and produce groups of sympathizers. When these groups get strong enough to “organize” themselves, they become ecclesiastical institutions with corporate ambitions of their own. The spirit of politics and the lust of dogmatic rule are then apt to enter and to contaminate the originally innocent thing; so that when we hear the word “religion” nowadays, we think inevitably of some “church” or other; and to some persons the word “church” suggests so much hypocrisy and tyranny and meanness and tenacity of superstition that in a wholesale undiscerning way they glory in saying that they are “down” on religion altogether. Even we who belong to churches do not exempt other churches than our own from the general condemnation. But in this course of lectures ecclesiastical institutions hardly concern us at all. The religious experience which we are studying is that which lives itself out within the private breast. First‐hand individual experience of this kind has always appeared as a heretical sort of innovation to those who witnessed its birth. Naked comes it into the world and lonely; and it has always, for a time at least, driven him who had it into the wilderness, often into the literal wilderness out of doors, where the Buddha, Jesus, Mohammed, St. Francis, George Fox, and so many others had to go. George Fox expresses well this isolation; and I can do no better at this point than read to you a page from his Journal, referring to the period of his youth when religion began to ferment within him seriously. “I fasted much,” Fox says, “walked abroad in solitary places many days, and often took my Bible, and sat in hollow trees and lonesome places until night came on; and frequently in the night walked mournfully about by myself; for I was a man of sorrows in the time of the first workings of the Lord in me.
