Thanks, everyone for your comments and responses. It will be very wonderful if the Orthodox happily return to Catholic Unity with the Holy Roman Church, which is the Mother of all the Churches, as the Council of Trent teaches us. When the Traditional Latin Mass was returned, it was Russian Orthodox Patriarch Alexei of Moscow who was one of the first to strongly support the right decision of the Holy Father Pope Benedict XVI, whereas even some shameless liberal so-called Catholic Bishops opposed it. The Orthodox are staunch Litirgical Traditionalists. They just have one or two confusions on a few doctrinal matters mainly because of one ot two bad Patriarchs.
Nearly 350 million Christians now live in this Schism, and what a Glorious Victory it will be for the Catholic Church and all Christendom were they to return. It's what Our Immaculate Mother asked for and promised at Fatima, as the best way to counter modern atheism, secularism and paganism
The below is from Pope Eugene IV's rejoicing Bull decreeing Holy Union with the Orthodox after the Council of Florence. While happily 22 sui iuris Eastern Churches still remain in full Catholic Communion with Rome, unfortunately, the greatly longed for and earnestly desired Union did not last.
May God grant we live to see the Union achieved. 1274 in Lyons II was the first attempt. Florence in 1438-1435 was the second. There may be a third attempt at Nicaea (for its seventeenth hundred anniversary) in 2025, per the Popes and Patriarchs.

[Definition of the holy ecumenical synod of Florence, presided by Pope Eugenius IV]Eugenius, bishop, servant of the servants of God, for an everlasting record. With the agreement of our most dear son John Palaeologus, illustrious emperor of the Romans, of the deputies of our venerable brothers the patriarchs and of other representatives of the eastern church, to the following.Let the heavens be glad and let the earth rejoice. For, the wall that divided the western and the eastern church has been removed, peace and harmony have returned, since the corner-stone, Christ, who made both one, has joined both sides with a very strong bond of love and peace, uniting and holding them together in a covenant of everlasting unity. After a long haze of grief and a dark and unlovely gloom of long-enduring strife, the radiance of hoped-for union has illuminated all.Let Mother Church also rejoice. For she now beholds her sons hitherto in disagreement returned to unity and peace, and she who hitherto wept at their separation now gives thanks to God with inexpressible joy at their truly marvellous harmony. Let all the faithful throughout the world, and those who go by the name of Christian, be glad with mother catholic church. For behold, western and eastern fathers after a very long period of disagreement and discord, submitting themselves to the perils of sea and land and having endured labours of all kinds, came together in this holy ecumenical council, joyful and eager in their desire for this most holy union and to restore intact the ancient love. In no way have they been frustrated in their intent. After a long and very toilsome investigation, at last by the clemency of the holy Spirit they have achieved this greatly desired and most holy union. Who, then, can adequately thank God for his gracious gifts?' Who would not stand amazed at the riches of such great divine mercy? Would not even an iron breast be softened by this immensity of heavenly condescension?These truly are works of God, not devices of human frailty. Hence they are to be accepted with extraordinary veneration and to be furthered with praises to God. To you praise, to you glory, to you thanks, O Christ, source of mercies, who have bestowed so much good on your spouse the catholic church and have manifested your miracles of mercy in our generation, so that all should proclaim your wonders. Great indeed and divine is the gift that God has bestowed on us. We have seen with our eyes what many before greatly desired yet could not behold.For when Latins and Greeks came together in this holy synod, they all strove that, among other things, the article about the procession of the holy Spirit should be discussed with the utmost care and assiduous investigation. Texts were produced from divine scriptures and many authorities of eastern and western holy doctors, some saying the holy Spirit proceeds from the Father and the Son, others saying the procession is from the Father through the Son. All were aiming at the same meaning in different words. The Greeks asserted that when they claim that the holy Spirit proceeds from the Father, they do not intend to exclude the Son; but because it seemed to them that the Latins assert that the holy Spirit proceeds from the Father and the Son as from two principles and two spirations, they refrained from saying that the holy Spirit proceeds from the Father and the Son. The Latins asserted that they say the holy Spirit proceeds from the Father and the Son not with the intention of excluding the Father from being the source and principle of all deity, that is of the Son and of the holy Spirit, nor to imply that the Son does not receive from the Father, because the holy Spirit proceeds from the Son, nor that they posit two principles or two spirations; but they assert that there is only one principle and a single spiration of the holy Spirit, as they have asserted hitherto. Since, then, one and the same meaning resulted from all this, they unanimously agreed and consented to the following holy and God-pleasing union, in the same sense and with one mind.In the name of the holy Trinity, Father, Son and holy Spirit, we define, with the approval of this holy universal council of Florence, that the following truth of faith shall be believed and accepted by all Christians and thus shall all profess it: that the holy Spirit is eternally from the Father and the Son, and has his essence and his subsistent being from the Father together with the Son, and proceeds from both eternally as from one principle and a single spiration. We declare that when holy doctors and fathers say that the holy Spirit proceeds from the Father through the Son, this bears the sense that thereby also the Son should be signified, according to the Greeks indeed as cause, and according to the Latins as principle of the subsistence of the holy Spirit, just like the Father.And since the Father gave to his only-begotten Son in begetting him everything the Father has, except to be the Father, so the Son has eternally from the Father, by whom he was eternally begotten, this also, namely that the holy Spirit proceeds from the Son."
