The study focuses on Archimandrite Spyridon (Kislyakov), the widely known early XX century Russian missionary. The paper reviews the forms and methods of Archimandrite Spyridon’s evangelical activities during his prison ministry (1901–1905). This period is of particular interest because Archimandrite Spyridon not only delivered sermons at prisons of the Nerchinsk forced labour camp but also wrote them down. The objective of the study is to establish distinctive features of the prison ministry in the context of the early XX century before the revolution,
to review the main missionary goals and objectives of the prison ministry and to analyse the homiletic legacy resulting from Archimandrite Spyridon’s prison ministry at the Nerchinsk forced labour camp.
