“Religion is for those who don't want to go to hell, and spirituality is for those who have already been there.”

Commonly attributed to Deloria on the internet, or sometimes to a few others, but without legitimate sourcing, the earliest variant of this yet located is a single quotation in Awakened India Vo. 99 (1994) p. 327, ascribed to Fr. Patrick Collins, University of Notre Dame, USA:
Religion is for those who are afraid of going to hell. Spirituality is for those who know they have been there — perhaps through involvement with religion.
The next variant located is ascribed to an anonymous member of Alcoholics Anonymous in Illuminating the Heart: Steps Toward a More Spiritual Marriage (1996) by Barbara G. Markway, p. 28:
Religion is for people who are afraid of going to hell; spirituality is for those who have been there.
A variant also occurs in The Higher Power of the Twelve-Step Program: For Believers & Non-Believers (2001), by Glenn F. Chesnut, Ch. 1 : Discovering a Higher Power:
Religion is for people who're afraid of going to hell; twelvestep spirituality is for those who've been there.

Cabal of the Cheval Pegasus (1585)
Context: The fools of the world have been those who have established religions, ceremonies, laws, faith, rule of life. The greatest asses of the world are those who, lacking all understanding and instruction, and void of all civil life and custom, rot in perpetual pedantry; those who by the grace of heaven would reform obscure and corrupted faith, salve the cruelties of perverted religion and remove abuse of superstitions, mending the rents in their vesture. It is not they who indulge impious curiosity or who are ever seeking the secrets of nature, and reckoning the courses of the stars. Observe whether they have been busy with the secret causes of things, or if they have condoned the destruction of kingdoms, the dispersion of peoples, fires, blood, ruin or extermination; whether they seek the destruction of the whole world that it may belong to them: in order that the poor soul may be saved, that an edifice may be raised in heaven, that treasure may be laid up in that blessed land, caring naught for fame, profit or glory in this frail and uncertain life, but only for that other most certain and eternal life.

Context: Our hearts go out to those who may have been injured. It’s still an active situation. And Germany is one of our closest allies, so we are going to pledge all the support that they may need in dealing with these circumstances. It's a good reminder of something that I've said over the last couple of weeks, which is our way of life -- our freedoms, our ability to go about our business every day, raising our kids and seeing them grow up and graduate from high school -- and now about to leave their dad -- (laughter) -- I'm sorry, I'm getting a little too personal -- getting a little too personal there -- (laughter) -- that depends on law enforcement. It depends on the men and women in uniform every single day who are, under some of the most adverse circumstances imaginable at times, making sure to keep us safe.

As quoted in O₂ : Breathing New Life Into Faith (2008) by Richard Dahlstrom, Ch. 4 : Artisans of Hope: Stepping into God's Kingdom Story, p. 63; this source is disputed as it does not cite an original document for the quote. It is also used in <i> The White Rose </i> (1991) by Lillian Garrett-Groag, a monologue during Sophie's interrogation.

Context: The real damage is done by those millions who want to "survive." The honest men who just want to be left in peace. Those who don't want their little lives disturbed by anything bigger than themselves. Those with no sides and no causes. Those who won't take measure of their own strength, for fear of antagonizing their own weakness. Those who don't like to make waves — or enemies. Those for whom freedom, honor, truth, and principles are only literature. Those who live small, mate small, die small. It's the reductionist approach to life: if you keep it small, you'll keep it under control. If you don't make any noise, the bogeyman won't find you. But it's all an illusion, because they die too, those people who roll up their spirits into tiny little balls so as to be safe. Safe?! From what? Life is always on the edge of death; narrow streets lead to the same place as wide avenues, and a little candle burns itself out just like a flaming torch does. I choose my own way to burn.
