Schisms and Sects

Written by: Beth Davies-Stofka

The two churches also developed different positions on a variety of leadership issues. The western Church discouraged marriage of priests and bishops, while the eastern Church allowed it. The western Church insisted that the pope was the first among bishops and the supreme authority, while the eastern Church encouraged more autonomy for local churches and their leaders, including the patriarch at Constantinople, and attributed supreme authority to the councils of bishops.

The formal or official schism of 1054 resulted not from one specific event or argument, but from powerful differences in geography, culture, politics, and Christian doctrine. The geographical, linguistic, and theological distances between the two churches, their different ways of worshipping, and their different styles of internal organization and authority, resulted in two very different churches.

At the local and regional level, there was varying awareness of these differences, but the Crusades made the differences apparent on all levels. In March of 1095, Pope Urban II, with ambassadors from Constantinople at his side, made a passionate appeal for Christian soldiers to help free formerly Christian lands from Muslim rule.

Pope Urban II was able to maintain harmonious relations between the Christian soldiers from the west and the Christians of the east. But after Urban's death in 1099, bishops from the western tradition were appointed to the traditionally eastern patriarchates of Jerusalem and Antioch.  The introduction of western-style worship and hierarchy made the differences between the two churches immediately visible. The differences were made more painfully clear in 1204, when Christian soldiers sent from Rome to Egypt diverted to Constantinople, sacking it and driving the Byzantines into exile.

From this point forward, Christianity would be divided into an eastern Church and a western Church.
