The Church has her origin with Jesus Christ and the Holy Spirit, not
with a human teacher, or group, nor a code of conduct or religious
philosophy. Orthodoxy believes that the Church has her origin in the
Apostolic Community called into being by Jesus Christ, and enlivened
by the Holy Spirit. The Feast of Pentecost, which is celebrated fifty
days after Easter, commemorates the "outpouring'' of the Holy Spirit
upon the Apostles and marks the beginning of the mission of the Church
to the world. The Orthodox Church believes that she has maintained a
direct and unbroken continuity of love, faith, and order with the
Church of Christ born in the Pentecost experience.
It is important to remember that back then, we didn't think of
ourselves as the "Orthodox Church" as such, because there was one Holy
and Undivided Church without schism, denomination, or division.
Although it is difficult to date the exact year of the schism, in the
year 1054 official charges, known as Anathamas, were exchanged. The
Crusades, and especially the sack of the city of Constantinople by the
western crusaders in 1204, can be considered the final element in the
process of estrangement and deepening mistrust. From that period
onward, the Western Church, centered about the Pope of Rome, and the
Eastern Church, centered about the Patriarch of Constantinople, went
their separate ways. Although there were attempts to restore communion
in the years 1274 and 1439, there was no lasting unity achieved. While
political, cultural, and emotional factors have always been involved,
the Orthodox Church believes that the two principal reasons for the
continued schism are the papal claims of universal jurisdiction and
infallibility, as well as the meaning of the Filioque.
The Eastern Church has continued in her teachings and Traditions - One
writer has compared Orthodoxy to the faith of Rome and Protestantism
in this basic fashion: Orthodoxy has maintained the New Testament
tradition, whereas Rome has often added to it and Protestantism
subtracted from it. For example, Rome added to the ancient Creed of
the Church, while numerous Protestant Churches rarely study or recite
it. Rome has layers of ecclesiastical authority; much of Protestantism
is anti-hierarchical or even “independent” in polity. Rome introduced
indulgences and purgatory; in reaction, Protestantism has shied from
good works and discipline.
In these and other matters, the Orthodox Church has steadfastly
maintained the Apostolic Faith. She has avoided both the excesses of
papal rule and of congregational independence. She understands the
clergy as servants of Christ and His people and not as a special
privileged class. She preserved the Apostles’ doctrine of the return
of Christ at the end of the age, of the last judgement and eternal
life, and continues to encourage her people to grow in Christ through
union with Him. In a word, Orthodox Christianity has maintained the
Faith “once for all delivered to the saints.”
