“It is a wonder that any religious at all preserves a love for the true spirit of religious life in the midst of all these adversaries, and remains resolved to be really spiritual in spite of them and even of hell itself. Although their number is small, it does not matter. These few sparks will help to keep the religious state alive to God's honor and glory. p. 188”

Address on Laying the Cornerstone of the Bunker Hill Monument (1825)
Context: If the true spark of religious and civil liberty be kindled, it will burn. Human agency cannot extinguish it. Like the earth's central fire, it may be smothered for a time; the ocean may overwhelm it; mountains may press it down; but its inherent and unconquerable force will heave both the ocean and the land, and at some time or other, in some place or other, the volcano will break out and flame up to heaven.

Indian Spirituality and Life (1919)
Context: The highest spirituality indeed moves in a free and wide air far above that lower stage of seeking which is governed by religious form and dogma; it does not easily bear their limitations and, even when it admits, it transcends them; it lives in an experience which to the formal religious mind is unintelligible. But man does not arrive immediately at that highest inner elevation and, if it were demanded from him at once, he would never arrive there. At first he needs lower supports and stages of ascent; he asks for some scaffolding of dogma, worship, image, sign, form, symbol, some indulgence and permission of mixed half-natural motive on which he can stand while he builds up in him the temple of the spirit. Only when the temple is completed, can the supports be removed, the scaffolding disappear. The religious culture which now goes by the name of Hinduism not only fulfilled this purpose, but, unlike certain credal religions, it knew its purpose. It gave itself no name, because it set itself no sectarian limits; it claimed no universal adhesion, asserted no sole infallible dogma, set up no single narrow path or gate of salvation; it was less a creed or cult than a continuously enlarging tradition of the Godward endeavour of the human spirit. An immense many-sided many-staged provision for a spiritual self-building and self-finding, it had some right to speak of itself by the only name it knew, the eternal religion, Sanâtana Dharma. It is only if we have a just and right appreciation of this sense and spirit of Indian religion that we can come to an understanding of the true sense and spirit of Indian culture.

Streatfeild. This first edition of <cite>The Way of All Flesh</cite> is widely available in plain text on the internet, but readers of facsimiles of the first edition should be aware that Streatfeild significantly altered and edited Butler's text, "regularizing" the punctuation and removing most of Butler's most trenchant criticism of Victorian society and conventional pieties. Butler's full manuscript, entitled <cite>Ernest Pontifex, or The Way of All Flesh</cite>, was edited and issued by Daniel F. Howard in 1965. It is from this edition that this quote is derived; it was excised by Streatfeild in the first edition.
