The Armenian Catholic Church is an Eastern Catholic Church in communion with the Pope in Rome. What that means is that a member of a local Catholic Church and a member of the Armenian Catholic Church are essentially the same. The Apostle Peter is considered to be the first Pope and founder of Roman Catholicism. Tradition tells us that the Eastern churches were formed by others of Jesus's Apostles after his death and resurrection. It is interesting to note that many of the Eastern churches have been in and out of communion with Rome, and that most if not all of the Eastern churches (19+ from different parts of the world) have counterpart churches with virtually the same traditions which are not in communion with Rome. Roman Catholics can attend Masses and take Communion in Eastern Catholic Churches and vice versa, but the liturgies (order of the Mass) will be very different.

Russian Orthodox chruch is part of the Orhtodox Cannon, the oldest form of Christianity. The Church is part of the same group that includes the Greek, Armenian and other ORthodox Churchs.
