 The naming of the liturgy after St Tikhon the Enlightener of America is based upon events that occurred when St Tikhon was the ruling bishop of the American diocese of the Russian Orthodox Church.Some Episcopalians who wished to become Orthodox asked Bishop Tikhon whether they might be allowed to continue to use their Anglican liturgy, that of the American 1928 "Book of Common Prayer" (BCP).He sent the BCP to Moscow, where a commission was appointed to examine the issue.
