1. introduction
Christianity tends to look backwards not forwards and be resistant to innovation. After all, I believe something miraculous happened back there... I'm also inspired considering the special attention of Calvinists of England were called the Puritan and Puritan Pilgrims which is in fact the same as a Scottish or English Calvinist, or a Dutch or Swiss Calvinist, dissimilar in John Knox and Presbyterianism. But Presbyterianism fits and is Calvinist and Reformed. What prevents the Calvinist Reformation from absorbing into the larger Orthodox Church? I did something flashy here about the prevention of the practice of Reformed Religion as invoked by Alabama and its works, are invoking guidance of a Reformed Religion from the Presbyterian fathers of the religion in the independent character of States. Which, has academic value, has merit, has Creedence with the living God and His Practices. Gov. G. Wallace" Government Greater than God": Let In the Church; Alabama (thepoliticalforums.com)

Churches don't pledge loyalty to political states. Churches aren't the loyal arm of a Government Cult with a high God chosen or elected to office like the old Japanese Emperor with his Holy Words spoken to the masses. Churches have never had a loyalty and pledge to fall down with a State until the PCUSA. If Churches fall down with States what a short history would have a "Roman Church", perhaps 100 years and ended. By comparison the Greeks setup a Church of local administrations praising a very "Present" roman secular system called 'byzantine". The Scottish Church sometimes existed without any support but the scottish people such as the Bishops War. The ethnic regional administrations during the Byzantine Empire in Orthodoxy produced many famous Armenian , and Greek generals and battles. The "Sees" and regional offices of Orthodoxy produce a famous document called a "Nicene Creed". At the start of this animation running from 0 AD to 1800 AD, the Hellenism of the Greeks inside the Greco-Roman Roman Empire, is popularly given way to a belief called Christianity (not established by a State). Similar beliefs exist in the head-god Zeus, that he had a half-human son Hercules by a human mother, notice then that the Creeds like Chalcedonian State, this isn't a half-man and half-god as Hercules was, Mary is a Birth-Giver, the Holy Spirit is untampered by human kind and unconfused, that the Holy Spirit fully Forms an unconfused human of Mary (and Joseph?) and a God of God before the world, contributing "Holy Spirit". Notice that Jesus Christ will defeat "Hades" without confusion or translation, the God in the underworld Hades will ferry those with coin to their unavoidable underground resting place under a sober watchman named Hades, Jesus Christ will descend to conquer Hades, release all the souls of all peoples in Hades and will arrive at a great New Jerusalem, a City on high. The democratic and debates administrations of the Great Nicene Church is depicted in Gold, the Popes agreed and assigned the "Nicene Creed". The Nicene Christianity forms One Church, there is only One Church. It is a mighty and Difficult church, that cast out arius, nestorius, monosyphites and miaphysites and John Knox repeated these words. Trinitarian and Nicene Christianity should be a key element of this One Nicene Church for the world as says the Reformation. The breakdown of unity is entirely secular, with thin theocratic arguments to excuse mass rampages like the 4th crusade or the Byzantines in Italy. In the animation, the Church splits in the middle with Catholic in yellow and Orthodox an earthen brown. As the Turkish-Ottomans sacked Constantinople, scholars fled with their scrolls throughout Europe causing spin-off movements called, Reformation, Humanism, Renaissance, with the Printing Press in the early 1500... Essentially called neo-classicism as well. The early Church was John Calvin's model for unity of a Church that the Pope trespassed with his tyrannical relations to the Church. ‘Better the Turkish Turban than the Papal Tiara’ - Byzantium: The Surprising Life Of A Medieval Empire (erenow.net)
The Animation of 1560 displays a Sky-blue Reformed Church in Scotland , Netherlands, Switzerland, and Hungary. The general "protestant" grouping of dark blue includes Lutheran, Anglican, and others. I'd invite without study all Protestant sects to a Reformed discussion, without having studied differences.

3. What prevents the helpful absorption of Christian Reformation by Orthodox
In the above paper, Puritans references the 760 AD Iconoclast movement within the Orthodox Church. Orthodox Christians did not believe in the worship of Icons with the perhaps relevant onslaught of Islam, where Mecca held far too many idols and is now replaced with the big "cube thing" and no idols are in Mecca, the start of Muhammad's conquests. Muslims routinely destroy the earlier arabic culture despite the Egyptian Pyramids as well as Egyptian tolerance, including the Copts (one of the sects rejected in the Nicene Church). Relevant or not, the Iconoclast movement for Christianity is a repeated action cited in Constantinople, or the Netherlands, or England, and the breaking and smashing of the marble statue typical of Rome, and a broken Mary statue may as well be the symbol of Reformed Church. As I cited, Mary as a BirthGiver in original Greek was not the Mother of Jesus Christ in many senses of the word. This forms one Church between Catholic and Orthodox factions during the Nicene Christian period. Naming factions of the Church is likely the most anti-Christian element of the Church at this period. During Woodrow Wilson's presidency, which represented the 'presentable' Confederate of America, was son of founders to Southern Presbyterianism, cited Greek Independence during the war, repetitively viewed the President Abraham Lincoln as a Pope in Religion. The Religious Covenants of a League of Nations pacified the 1st world wars in Europe, with a Pro-Christian focus, Wilson proposed a Wilsonian Armenia, Greece, Bulgaria, even Pontus... It suggested nearly an unstable Turkish identity on nearly every side and border. The Turks were briefly occupied in 1920 having lost World War 1 and the independent League of Nations of Orthodoxy. I've noticed Woodrow Wilson celebrated in most european and Asian countries like Korea as a return to the independence before the United Nations or the European Union, but most fervently it seems Armenia promotes the 4 times larger "wilsonian Armenia" borders treaty and there is a Wilson middle school. Presbyterian hints that the Creed in Greek would state "Presbyteros" for "ruling elders" in place of Bishops, which was a necessary phenomenon during the Scottish Bishops War.

4. What fuels the absorption of Reformed in Orthodox?
A necessary lesson of the war is that there was "strength" in the absorption of the Puritan Pilgrim tradition in the already similar and doctrinally identical Presbyterian Church of Nations, like North Ireland, Scotland, Wales... This is not similar to being identitical to the whole Reformed Communion of 80 million, not at all... It IS similar to ask what this Communion will accomplish with that identity, when, the model of Orthodoxy could not be met during the Ottoman occupations of 1500 to 1800, a brief window post 1900 to 1950 existed considering Woodrow Wilson believing the "native determination" of "whatever government established" by the peoples of Russia, so forth, would have been best, without opinions yet on Communism, and the States of Orthodoxy are now strongly religious and now not so much Communist in the 1992 to 2020 period.
We are at a different mission field entirely at my viewpoint in terms of communications and accomplishments. Would the Orthodox Church in America with its Armenian , Russian, Greek ethnic and heritage of services specific to the peoples in which Jesus entered to preach say in the Call of Macedon, in which Macedon the country today is a Orthodox Church, and carries traditions now nearly implicit in the Bible at Jesus Christ's instructions. Would they form a Puritan Pilgrim Orthodox Church an African American Orthodox Church and a Dutch Orthodox Church in America and a Scottish Orthodox Church in America? What fuels the absorption of Reformed in Orthodox is prolonged persecution during the President Eisenhower administration. While Alabama defended the Church to how it is historically organized... The Orthodox Church did not experience the 1960s change of American opinions on interracial marriage, where 90% were against it then and near 1980 90% were in favor of interracial marriage, and that did not happen in the Balkans. Eisenhower hallowed out All diversities of Presbyterian Religion into a Government religion that would defend Islam, Buddhists, and all prayer against Communism.... The historic "In God We Trust" seen on a banner of Oliver Cromwell 'who preferred the muhammeden to an irishman' would be put on money "in God we Trust". In honesty, such persecutions of one Church not performed on this entire world of division will prove to be discrimination. SO we see developments by year Eisenhower 1958, United Presbyterians, Reagen 1983, "PCUSA". The Reformed Religion does not form a large enough identification to suggest the humble submission to the One Church. The Reformation appears a bookish, insular Christianity, that headed off , and this (fits the narrative), the English Reformed, or Puritan Pilgrim, forms "My Country Tis of Thee" during Obama's inauguration, that we are all "experiencing" the freedom that does an English reformed person who must leave England at the return and persecutions of a Catholic Majority, to form communities in Massachussettes and Virginia during the English Civil War, and wrote a Westminster Confession confirming the franca lingua of Greek during the writing of the New Testament. I don't believe the "religious freedom" of "ANY" religious community is identical to the "religious freedom" of "ANY" other religious community, say an Arab Shia Muslim leaves the Sunni run countries and it forms a "Religious Freedom"? In that case "My Country Tis of Thee" is a total failure and is stated mockingly, as the firm staunch Westminster Confession subscribers the Southern Presbyterians are gone there is no "Author of Liberty", there is no one native to this lands recognized by all the other peoples native to all the other lands spoken to in a Christian Communion by the song. The My Country Tis of Thee doesn't tell the story we would expect whatsoever. Yet, there is no air of respect, ancient privilege granted to the Orthodox faith granted to the Presbyterian faith , or clout to have defense of itself as would be the Orthodox Church today with a Puritan Pilgrim Orthodox Church.
