What do Catholics and Eastern Orthodox disagree about, anyway?

Vatican City, Jun 30, 2016 / 03:08 am (CNA/EWTN News).- With the Eastern Orthodox wrapping up their “pan-Orthodox Council” this past weekend, it might be a good time to take a look at the factors that separate Catholics from their sister Churches in the east.

The main issues of disagreement are the primacy of the Bishop of Rome and elements of Trinitarian teaching, although conflict also exists over the Immaculate Conception, purgatory and other doctrines.

For 1,000 years after Christ, the Churches of east and west were in communion with one another, holding seven ecumenical councils between 325 and 787 to define Christian belief.

But throughout this time, the cultures of the Latin-speaking west and Greek-speaking east grew more and more estranged, and there was increasing distrust and hostility between them. Occasional schisms occurred but were healed – such as the Acacian schism of the late fifth century and the Photian schism of the 860s.

When's the last time the Photian Schism made the news?
