Abstract: This paper discusses historical dynamics in the Russian Eastern Orthodox Church, in particular among the groups known as Old Believers. Seeing itself as the only true continuation of ancient Christianity, Eastern Orthodoxy has been more concerned with continuity and institutional authority than with conversion into the faith, and therefore schism was regarded as a matter of utmost significance. The Great Schism of 1666 split the reforming central religious authorities from the plethora of Old Believers, so-called because they remained faithful to the truth of the old ways. Over later centuries the excommunicated Old Believers would themselves scatter and splinter repeatedly, in each case erecting boundaries around a newly defined (yet seen as ancient) righteous way of life, while also protecting it from the state law and external authority. In this paper I suggest that these schismatic decisions to adopt the stance of messianic “rightness,” and the willingness of martyrs to struggle for it, can be related to the moral-social basis of the Russian Revolution, especially if revolution is understood not simply as a political event but also as the forging of new and “true” meaning, accompanied by the rejection of wrongful thinkers.
