the Orthodox hold the Catholic Faith and have valid sacraments since their bishops have been validly ordained.
Let me know when the Orthodox Church accepts the Pope as head of their Church. Just the simple fact that Catholics feel they trace their lintage from Peter makes one wonder who the leader is of the Orthodox?
There is much more. It is nice to say the Orthodox and Catholics get along so well. But someone’s doctrine must be wrong. And that presents a problem when one claims their doctrine is guided by the Holy Spirit and the Church cannot be in error.
