Well I would not say that every issue it small. Their is not a United Christendom for many reasons. The mistakes of people of the past, hatred, misconceptions, and disagreements are the major reasons.
When somethings start they start off a chain-reaction. That reaction continues until the fuel is gone. The first split in the Church occured in the mid-eleventh century when the ambassador of the Pope marched into the greatest cathedral in Constantinople at the time walked up to the altar (during the service I think) and placed a papal bull of excommunication on it. He then turned around (which was probably in a pompus way) and walked off. The deacon or whatever standing by the altar picked it up and read it. He begged the ambassador to take it back (probably with tears in his eyes), but to no avail. Hence the Orthodox Church came into being. It was a mistake in my view to do such a thing, but then again I was not there.
**The Church then became corrupt./**B] So Matrin Luther came along and protested and started the great Protestant Revolt. Afterwards and it still continues today, Protestantism tears itself apart at such a rapid rate that today there are over 80,000 divisions. Tomarrow there will be 160,000. It all began with the mistake of being corrupted.
Then the attacks come along. Mostly because of misconceptions, hatred, and closed minds.
Christianity, Islam, Hinduism, Budhism, Paganism, Confucionism, and much much much more are all divided. The world is divided. Why can’t there be one religion, one nation, one ruler, and one government? That is easy to answer. Because we are human.
The only way that it would not be sinful for Christendom to unite is for Protestants to give up their heretical beliefs and join the Catholic Church. The Orthodox will have to accept the supremacy of the bishop of Rome (the pope). I hope and pray that this day will come. Any other way would be sinful against truth. God stands for truth for He is Truth.
God speed.

The Church has never been and can never be corrupt. It is quite a different thing saying some priests were corrupt. That was true. After all they are human with all the failings that go with that.
