Eastern Orthodox Christianity vs Roman Catholic

The Eastern Orthodox church is apostolic in its doctrine and dogma and it is the church of the first millennium and the Church of Christ. I want to debate a Catholic on the Papacy, papal supremacy, papal infallibility, purgatory immaculate conception, statuary, indulgences and other doctrines and dogmas that Catholics have that aren't apostolic and at times goes against the teachings of the church of the first millennium and the writings of the church fathers.
