What was the effect of the eastern orthodoxy schism?

Answer 1

Catholic Answer

The Great Schism in Catholic terminology (there is no "Roman Catholic" Church) refers to the time in the fourteen century was there was more than one claimant to the Papal throne. The Schism with the Orthodox Church is referred to as the Eastern Schism. The one lasting effect of the Eastern Schism is that the Eastern Church has been cut off from the rest of Christianity for over a millenium now. Each Eastern Rite split into two during the Eastern Schism so that now there is a Greek Uniate Rite, and a Greek Orthodox Church, and so on for the other Eastern Rites. Pope Benedict referred to this as the Church trying to breath on one lung. As the Modernist heresy worses and the secularization of the world becomes more breakneck, the Church must come back together to face the world united and to bring Christ to the world, which is so desperately in need of Him right now.

from A Catholic Dictionary, edited by Donald Attwater, Second edition, revised 1957

The Schism of the East the estrangement and severance from the Holy See of what is now called the Orthodox Eastern Church was a gradual process extending over centuries. After a number of minor schisms the first serious, though short, break was that of Photius; from then on tension between East and West increased, and the schism of Cerularius occurred in 1054. From then on the breach gradually widened and has been definitive since 1472. There was a formal union from the 2nd Council of Lyons in 1274 until 1282, and a more promising one after the Council of Florence from 1439 to 1472. After the capture of Constantinople it was in the Turkish interest to reopen and widen the breach with the powerful Roman church; the patriarchates of Alexandria, Antioch, and Jerusalem were dragged into this policy, Russia and the Slav churches stood out the longest of any: none of these churches, except Constantinople itself in 1472, formally and definitely broke away from the unity of the Church. But in the course of centuries the schism has set and crystallized into a definite separation from the Holy See of many million people with a true priesthood and valid sacraments. The origins, causes and development of the schism are matters of much complication, still not fully unraveled.

from Modern Catholic Dictionary by John A. Hardon, S.J. Doubleday & Co., Inc. Garden City, NY 1980

Separation of the Christian Churches of the East from unity with Rome. The schism was centuries in the making and finally became fixed in 1054, when the Patriarch of Constantinople, Michael Cerularisu (died 1059), was excommunicated by the papal legates for opposing the use of leavened bread by the Latin Church and removing the Pope's name from the diptychs or list of persons to be prayed for in the Eucharistic liturgy. A temporary reunion with Rome was effected by the Second Council of Lyons (1274) and the Council of Florence (1439) but never stabilized.
