The Russian Old Orthodox Church (Russian: Русская Древлеправославная Церковь) is an Eastern Orthodox Church of the Old Believers tradition, born of a schism within the Russian Orthodox Church (raskol) during the 17th century (Old Believers). This jurisdiction incorporated those Old Believer groups which refused to accept the authority of Belokrinitskaya Hierarchy, est. 1846 (see Russian Orthodox Old-Rite Church). It was also known as Novozybkov Hierarchy (by the name of the city where its chief hierarch resided in 1963–2000). It is considered to be independent of the Eastern Orthodox Communion i.e. it is not recognised by the Patriarch of Constantinople, nor by any of the Orthodox churches in communion with the Patriarch.
From 1963 until 2002, the official title of its chief hierarch was Archbishop of Novozybkov, Moscow and all Russia. In 2000, with the move of the Archbishop's residence to Moscow, the toponym Novozybkov was dropped from the title. Since March 2003, the official title of the church leader is Patriarch of Moscow and All Russia. The current head of the Church is Patriarch Alexander (Kalinin; since 9 May 2000, Patriarch since 3 March 2003) [1].
The Russian Old Orthodox Church was formed from the groups of Old Believers who insisted on preserving the traditional church structure and hierarchy (as opposed to Bespopovtsy groups), but refused to accept the authority of Metropolitan Amvrosii (Popovitch) who converted in 1846 and founded the Belokrinitskaya Hierarchy, due to some canonical problems with his conversion and the ordination of its second bishop, Kiril (Amvrosii ordained him alone, which was against canons). These Old Believers groups continued to exist without a bishop until 1923 when they created their own hierarchy, by receiving the Renovationist Archbishop Nikola (Pozdnev) of Saratov (1853–1934). He was received (like Amvrosii in 1846) by chrismation on November 4, 1923 and given a title Archbishop of Moscow, Saratov and all old Orthodox Christians of Russia. Some problems with Nikola's installation and with the 'validity' of this jurisdiction in general was that the Renovationist Church was a schism from the Russian Orthodox Church and archbishop Nikola, together with other Renovationist clergy was officially suspended from all priestly functions by the Council of Bishops under Patriarch Tikhon (Bellavin) in 1923. Also, some Old Believers had doubts whether Nikola was baptized by infusion rather than triple immersion (see Baptism). These doubts were rejected by the Moscow Council of the Old-Orthodox Church in May 1924.
