The necessity of provide relics for antimensions in new churches often necessitates continuous division of relics. An account of this process can be found in a treatise of a pre-revolutionary Russian church historian Nikolay Romansky (ru). According to Romansky, the Holy Synod of the Russian Orthodox Church operated a special office, located in the Church of Philip the Apostle in the Moscow Kremlin, where bones of numerous saints, authenticated by the church's hierarchs, were stored, and pieces of them were prayerfully separated to be sent to the dioceses that needed to place them into new antimensions.
