Executive summary

Primary documentary evidence for early Soviet persecution of Christians takes the form of Bolshevik decrees and party resolutions (notably Lenin’s 1918 church–state separation decree and 10th Party Congress policy), contemporaneous church communications and encyclicals (most famously Patriarch Tikhon’s January 19, 1918 anathematization), Soviet administrative and criminal-law instruments used to arrest clergy, and later testimony and archival compilations (including congressional hearings and wartime memoranda) that cite police actions, closures and killings; the reporting assembled here identifies those documentary strands while noting that many cited sources in this collection are secondary summaries that point to—rather than reproduce—original documents [1] [2] [3] [4] [5] [6].

1. Lenin’s legal architecture: the 1918 decree that stripped the church of rights

The clearest primary starting point is the Bolshevik legal framework: Lenin’s decree on the separation of church and state in early 1918 removed the Orthodox Church’s legal personhood, property rights and ability to teach religion to minors, a statute repeatedly cited as the legal basis for expropriations and restrictions on worship [1] [4]. Contemporary party texts and press carried the same line—treating religion as an obstacle to communist construction and promoting “militant atheism,” language that Lenin himself urged be militant and irreconcilable toward religion [1].

2. Party resolutions and anti‑religious campaigns: the 10th Congress and the 1921–1928 phase

Party resolutions adopted at the 10th CPSU congress and subsequent anti‑religious campaigns (1921–1928) constitute another documentary tier: the congress-level decisions launched policy measures that intensified harassment of churches, created schisms the state manipulated, and set patterns of propaganda and legal prohibition that culminated in later legislation banning public religious activity [2]. Secondary syntheses in the sources trace these resolutions as the formal templates used by local soviets and security organs to criminalize priestly and lay practice [2] [4].

3. Church records and clergy communications: Tikhon’s encyclical and accounts of violence

Primary church materials and clerical communications document responses and episodes of violence: Patriarch Tikhon’s 19 January 1918 encyclical anathematizing those committing violence is repeatedly cited as a contemporaneous Orthodox record of conflict between church leaders and Bolshevik authorities, and accounts of shootings at processions and arrests during the Civil War are recorded in church and local reports of the period [3] [7]. Those church documents remain central primary-source evidence of persecution even where later historians debate interpretation.

4. Administrative tools and statistics: confiscations, killings and the League of the Godless

State administrative instruments appear in primary form across decrees, criminal‑code articles and the founding of organizations like the League of Militant Atheists that formalized anti‑religious propaganda; contemporary Soviet statistics, internal reports and later compilations claim mass expropriation of church land and property and, according to cited summaries, the killing of dozens of bishops and over a thousand priests in the 1922–1926 window—figures that derive from archival counts and published Soviet-era datasets collected by scholars [4] [8]. The sources assembled here point to those original decrees and institutional records as documentary proof.

5. Security reports, hearings and diplomatic memoranda: corroboration and later testimony

Testimony and governmental hearings compiled after the fact supply another primary-source layer: U.S. congressional hearings on Soviet religious persecution include witness testimony and documentary exhibits; wartime memoranda and Vatican files referenced in diplomatic histories record Soviet anti‑Catholic and anti‑Orthodox measures and Soviet propaganda strategies, providing corroborative archival traces [5] [6]. Contemporary Western research starters and archival studies also quote security‑service files and province-level counts of closed churches and arrested clergy [9].

6. Limits, interpretations and competing narratives

The documentary record is extensive but contested: secondary sources warn that many narratives rely on church‑produced documents and émigré compilations that emphasize brutality, while other archival research stresses pragmatic shifts (for example, temporary wartime relaxation under Stalin) and the uneven application of policy across regions; the sources used here are mainly secondary summaries that point to original decrees, encyclicals, party resolutions and archival testimonies rather than reproducing all primary documents in full, so researchers should consult state and ecclesiastical archives (decrees, provincial police files, Patriarchal correspondence, CPSU congress records and Vatican memoranda) for original text and context [10] [6] [8].
