The roots of the current “spiritual but not religious” movement (if one can call it a movement, since it isn’t organized as such) got a great boost from the addiction recovery movement of the 1990s. The connections are both theological and sociological. Oddly enough, the roots of the addiction recovery ethos, particularly as advanced by Alcoholics Anonymous, comes from an evangelical Christian para-church group of the early 1900s known as The Oxford Group, led by Lutheran minister Frank Buchman. You can read more about this in my book *Victims & Sinners: Spiritual Roots of Addiction and Recovery.* What do you see as potential connections or disconnections between the “SBNR” upsurge and addiction recovery movement?
