"Of these heresies diffused, with what sufferings the LORD hath known, over a great part of the world, was formerly Arianism, and at present is the Papacy. This, too, as the former has become extinct, although now flourishing, shall not endure, but pass away and be cast down, and a great voice from heaven shall cry: It is cast down (Rev. xii. 10)."
Encyclical of the Eastern [Orthodox] Patriarchs, 1848
"the Orthodox Church has never ceased to intimate to the Papal Church, having clearly and explicitly set forth that so long as the latter perseveres in her innovations, and the orthodox Church adheres to the divine and apostolic traditions of Christianity, during which the Western Churches were of the same mind and were united with the Churches of the East, so long is it a vain and empty thing to talk of union."
The Patriarchal Encyclical of 1895 [of Constantinople]
"to any sound-thinking Orthodox person the idea could not occur to receive communion in a Protestant or Catholic church, and this because with all his being, organically, he knows with an inner intelligible knowledge that there is no holy Communion anywhere but in the Church of Christ ... . There is God, there is His One, only Holy, Apostolic Church, and there is the whole human race, all called to God through His holy Church. All other religions, so-called Christian, monotheistic or pagan, all without the slightest exception, whether it be Catholicism, Protestantism, Islam or Buddhism—all are obstacles placed by the devil as his traps between the Church of Christ and the whole human race."
A Report to the Sobor of Bishops of the Russian Orthodox Church Outside of Russia
by Archbishop Vitaly of Montreal and Canada
"We believe that our holy Orthodox Church is the One, Holy, Catholic and Apostolic Church of Christ, which possesses the fulness of grace and truth and, in consequence thereof, unbroken apostolic succession.
On the contrary, the "churches" and "confessions" of the West, having in many ways perverted the Faith of the Gospel, the apostles and the fathers, are deprived of sanctifying grace, of real mysteries and apostolic succession.
The Holy Mountain is convinced, not without great anxiety, that although the Orthodox are making many concessions and compromises to the Roman Catholics, the latter antithetically continue to adhere to their own errors which have served as the cause of their schism from the Orthodox Church and later led to the Protestant split. Thus, the Pope, during his visit to the center of Orthodoxy in the patriarchal cathedral, did not in the least hesitate to proclaim that he was coming to Constantinople as the successor of Peter, "who as the ultimate authority has the responsibility of superintending the unity of all, to guarantee the agreement of the Church of God in fidelity and in the 'faith which was once delivered unto the saints' (Jude 3)" (Episkepsis, ibid., p. 9). In other words, the Pope defended (papal) infallibility and primacy; and there are many other actions and manifestations which the Pope has effected on behalf of uniatism. We remember the establishment of diplomatic relations between the Greek Government and the Vatican which, even though it may justify papism, is unjust and strikes out at the Mother and Nourisher of our [Greek] nation, the Orthodox Church."
The Announcement of the Extraordinary Joint Conference of the Sacred Community of the Holy Mount Athos
" ... the Pope was received as though he were a canonical (proper) bishop of Rome. During the service, the Pope wore an omophoron; he was addressed by the Ecumenical Patriarch with the greeting “blessed is the one who comes in the name of the Lord” as though it were Christ the Lord; he blessed the congregation and he was commemorated as “most holy” and “His Beatitude the Bishop of Rome”. Furthermore, all of the Pope’s officiating clergy wore an omophoron during the Orthodox Divine Liturgy; also, the reciting of the Lord’s Prayer, his liturgical embrace with the Patriarch, were displays of something more than common prayer. And all of this, when the papist institution has not budged at all from its heretical teachings and its policy; on the contrary, the Pope is in fact visibly promoting and trying to reinforce Unia along with the Papist dogmas on primacy and infallibility, and is going even further, with inter-faith common prayers and the pan-religious hegemony of the Pope of Rome that is discerned therein."

The Orthodox don't 'need'
the Catholics ... Catholics need Orthodoxy!
