Reformed Churchmen

We are Confessional Calvinists and a Prayer Book Church-people. In 2012, we remembered the 350th anniversary of the 1662 Book of Common Prayer; also, we remembered the 450th anniversary of John Jewel's sober, scholarly, and Reformed "An Apology of the Church of England." In 2013, we remembered the publication of the "Heidelberg Catechism" and the influence of Reformed theologians in England, including Heinrich Bullinger's Decades. For 2014: Tyndale's NT translation. For 2015, John Roger, Rowland Taylor and Bishop John Hooper's martyrdom, burned at the stakes. Books of the month. December 2014: Alan Jacob's "Book of Common Prayer" at: January 2015: A.F. Pollard's "Thomas Cranmer and the English Reformation: 1489-1556" at: February 2015: Jaspar Ridley's "Thomas Cranmer" at:

6 July 1054 A.D. Schism between East and West

6 July 1054 A.D.  Schism between East and West

Graves, Dan. “Schism Between East and West Began.”  Apr 2007.  Accessed 7 May 2014.

The division of the Roman Empire into halves was eventually echoed in the church. The break came when Michael Cerularius was Patriarch of Constantinople and St. Leo pope in Rome. In 1053, Cerularius circulated a treatise criticizing in strong terms the practices of the Western church. Catholics did not allow their clergy to marry. This was contrary to scripture and tradition, said Cerularius. And Catholics used unleavened bread in their Eucharist. But the most serious concern was that the Latin church had added the word "filoque" to the Nicene creed, saying the Holy Spirit proceeded from both Father and Son.

It would seem that this was more political to Leo than religious, as it was pressed upon him by the Franks. Cerularius excommunicated all bishops of Constantinople who used the Western ritual and closed down their churches. This incensed Leo. He demanded that Cerularius submit to the pope. Any church which refused to recognize the pontiff as supreme was an assembly of heretics, he said--a synagogue of Satan. The Eastern patriarch wasn't about to accept this characterization. The five patriarchs, Antioch, Jerusalem, Alexandria, Constantinople and Rome were equals in his eyes. The bishop of Rome, as patriarch of the West, was given the courtesy title of "first among equals" and in a tie vote he could make the final determination according to tradition. Rome's growing claims to authority were deemed unacceptable to the other patriarchs, who believed (and who still believe) that Christ alone is the head of the church.

Leo sent legates, headed by an unyielding man, Cardinal Humbert, to discuss the issues. Before they could complete their mission, Leo died. Humbert was so rude to Cerularius that Cerularius refused to speak with him. Aggravated by this treatment, the legates marched into St. Sophia on this day, July 6, 1054, and placed a bull on the altar, excommunicating Cerularius. After this act, Humbert made a grand exit, shaking the dust off his feet and calling on God to judge.

Cerularius convoked a council and once more blasted Western practices. Humbert was anathematized. The Orthodox condemned all who had drawn up the bull. There was no chance of reconciliation between the factions. The once-united Church was now divided into two: Eastern Orthodox and Roman Catholic. In many areas, Orthodox churches submitted to Rome while maintaining many of their rites and traditions. These became the Byzantine rite or Uniate churches, which still exist in countries as distant in time and place as the United States.

The rift was inevitable. Traditions and doctrine had been diverging for hundreds of years. East and West would be even farther apart after the cruelties of the crusaders, whose violent acts were often against fellow-believers of the East whom, in ignorance they did not recognize as Christians. The unity of love which Christ had said should mark his followers was broken.
