The Eastern Schism with Rome, which was finalized largely in 1472, happened. It cannot be denied. After a long series of quarrels and bad feelings between eastern and western Catholics, the Bishops of (most of) the Eastern Churches (called Patriarchs) decided to break communion with the See of Rome. The result, which still remains today for most of those who left, is that the (so-called) "Eastern Orthodox" Churches are disconnected with the majority of their brethren in Christ. There are a number of eastern Churches who have returned to full communion with Rome, and they are properly called "Eastern Catholics".
The Protestant departure from the Catholic Church in the 16th century happened; no one can deny that either. Even though it mainly occurred in Europe, the results can be seen today throughout the world. Protestant congregations abound and thousands of protestant denominations have been formed. The Catholic Church has, for the last 500 years, sought to restore the descendants of those original Protestants back into communion with the Roman Catholic Church that Christ founded 2000 years ago. Some have returned, many have not. All of those who descended from this protesting revolt are western in form and manner, which is distinctly different from the "Eastern Orthodox" mentioned above.
It is easy to see what happened to the Eastern Orthodox who returned to full communion and became the Eastern Catholics. They retained the vast majority of the faith, and saw the need for full communion. They rejected the quarrel and realized that it is not right to be separated from the Vicar of Christ on Earth. Their liturgies and practises were retained during the time of their schism, and since these were distinctly Catholic (albeit of an Eastern flavor), the spirituality and grace present in them led them back to the fold. For which, we praise God in His mercy for granting this to them, and pray that He will do the same for those still caught in the schismatic "Orthodox" Churches.
In Protestantism, however, it is a bit less clear to see what happened. This is particularly so because the Protestants broke with Catholic practice to such a degree that they lost the essentials of what makes a Church to be a Church. This is why protestantism is not said to be a Church, but rather a collection of "ecclesial communities". They do not have the fullness of the sacraments (the way that the Eastern Orthodox still do), because they intentionally chose to reject a major portion of the historic Christian faith. In other words, some in the East broke and stayed as valid Churches; the protestants in the west broke and gave up being Churches.
Therefore, we can ask the question of what it is that brings Protestants back into the fold of Catholicism? They do not have valid sacraments (other than baptism and marriage--which is another story), and they have chopped out sections of the Bible; what, therefore, is it that remains to bring them back? Now, we must admit, God can work conversion any way that He wants to do so; He is not bound by our limitations, so I am not speaking at all about His Almighty Power. I am asking the question about protestantism itself: what raw materials are available in the practice of protestantism that God can use to convert the "lost sheep" back into the fullness of the Catholic faith?
One thing that many converts from protestantism will tell you is that they found things in the Bible that pointed them to the Catholic Church (after all, even though Protestants have less than the whole Bible, they still have some of it, and what they have has mostly been translated well enough to see the Catholic faith in it). Another thing that they have--although it is not a part of protestantism per se--is the simple facts of history. It is hard to deny that history supports the Catholic Church's claim to exclusive authority from Christ; once a Protestant sees history for what it is, it is hard to remain a Protestant.
There is something else, though, that has led many a Protestant back into the Catholic Church. It might not be what many would expect, because it is not often spoken of, but its branches extend far and wide, and it has a great impact on a large number of Protestants today. What I am speaking about it English Catholicism. No, "English Catholicism" is not referring to a distinct "branch" of the Catholic Church, nor is it talking about what is currently present in Catholic Churches in England (after the protestant departure, English Catholics mostly tried to be "more like Rome" in their practice of the faith--which was a great idea). It does not even refer specifically to the English language. It is referring, rather, to a set of Catholic cultural practises that found a unique manner in ancient England and remained for centuries after (even when some tried to destroy them!).
It is this fact of English Catholicism surviving the protestant split with Rome that I wish to consider in depth. Some may think it an accident, but God does not use accidents -- He is almighty and sovereign and does things intentionally. Others might say that what I am referring to is just a useless detail of history; that also is a mistake. Still others may not give it much thought. When we look at history and Catholic theology we find that even in the midst of the worst experiences (like the departure of the protestants in the 16th century) God is always working behind the scenes and doing things beyond what we can expect.
