This is a really good summary of the Schism from the Orthodox POV.

In particular, read the section entitled, “Papal Supremacy and Pentarchy.” A lot is boiled down right there, and by following the hot link to “Primus Inter Pares” in the final sentence of that section.

Rome is welcome to rejoin the Orthodox church. All it has to do is renounce the deep seated heresies that caused the split to occur and worsen over the years.
