I traveled to the Former Soviet Union 5 times (1992, 1997, 2007, 2011, 2015) for more than a year total time, to visit and document Spiritual Christian communities. While visiting nearly 100 Spiritual Christian congregations around the world, differences between the often confused faiths became clear to me.
My summary findings here and at are updated as time permits.
Can you imagine someone who calls everyone "dude," never learning peoples' real names?
Not knowing alternatives is dangerous in professions where we expect expertise.
Would you trust a dentist who only fixes teeth by pulling them because he/she does not know what else to do?
* The term "Spiritual Christianity" (Russian: dukhovnoe khristianstvo) specifically refers to "Russian folk Protestantism," not all of the 100 types of sectarians (Russian: sektanty).
The phrase was used by Molokane to and other heretics to describe themselves, and was popularized in scientific literature by Moscow Professor Alexander Ilyich Klibanov (1910-1994), a historian, religious scholar, and pioneering researcher of religious and social movements in Russia.
Though many resisted name hijacking, the false identity transformation was gradually adopted until it passed a tipping-point by W. II, probably because: Let's heal the fear, lies, and shame. The false label confuses histories of diverse faiths which are not Molokan, and should not be used except for actual Molokane.
