Saint Tikhon of Moscow's contribution to the Western Rite has been more enduring. While he was bishop of the 's diocese in America, some Episcopalians were interested in joining Orthodoxy while retaining Anglican liturgical practices. Tikhon, sent the 1892 "Book of Common Prayer", enquired about the viability of Orthodox parishes composed of former Anglicans using Anglican liturgical practices. In 1904, the Holy Synod concluded that such parishes were possible and provided a list of doctrinal corrections to the "Book of Common Prayer" text of the prayers and rites that were necessary to profess in Orthodox worship. The Holy Synod also concluded that detailed changes in the "Book of Common Prayer" and in Anglican liturgical practices, together with compilations of new prayers, and entire rites, can only be carried out on location in America and not from Moscow. While Tikhon did not receive any Episcopalians as none approached him for reception into the , his efforts laid the groundwork for the later reception of Episcopalians into the following the 1975 revision of the "Book of Common Prayer".
