what is the difference between catholicism and eastern orthodox
Theological differences between the Catholic Church and the Eastern Orthodox Church Main points of discontent for the Catholic Church are the papal primacy[1][2][3] and the filioque clause.[1][2] For Eastern Orthodox the main point of discontent is voiced by neo-Palamism, which sees the essence-energy distinction, and the experiential vision of God as attained in theoria and theosis, as the main point of divergence between East and West.

Seven churches of Asia The "churches" in this context refers to the community or local congregations of Christians living in each city, and not merely to the building or buildings in which they gathered for worship.[2][3]
Diocese The Eastern Orthodox Church calls dioceses episkopÄ“ in the Greek tradition and eparchies in the Slavic tradition.[citation needed]
