The long East–West rupture

Church History · ninth–thirteenth centuries

The estrangement of Rome and Constantinople grew through disputes over authority, the Filioque, language, and political events. The exchange of censures in 1054 marks a famous episode, while the 1204 sack of Constantinople deepened the rupture.

Historical context

The relationship did not change from full unity to complete separation in a single day. Later efforts at reunion and the lifting of the 1054 censures in 1965 are distinct from restoration of full communion.

Key points

Primary sources

John of Damascus writes:

Before the later rupture, John of Damascus used Father-through-the-Son language for the Spirit; this is vocabulary evidence, not proof that later Latin and Greek formulas were identical.

proceeding from the Father and communicated through the Son, and participated in by all creation

— St. John of Damascus, An Exact Exposition of the Orthodox Faith (Book 1, Chapter 8), trans. E. W. Watson and L. Pullan

Passage context and translation

John names the Father as the Spirit's sole source of eternal procession and also describes the Spirit as communicated through the Son. Later in this chapter he explicitly says the Spirit is not 'from the Son' but is manifested and imparted to us through the Son. The excerpt must not be read as John endorsing a later Latin Filioque formula.

Before the excerpt

the Spirit of God, direct, authoritative, the fountain of wisdom, and life, and holiness

After the excerpt

through Himself creating, and investing with essence and sanctifying, and maintaining the universe

Watson and Pullan translation in Nicene and Post-Nicene Fathers, Second Series, Volume 9; the wording is a clause in I.8. Read with I.8's later distinction between procession from the Father and manifestation through the Son.
