Okay, this may seem an odd thread to start but I'm talking about history here.
I'm not criticising or promoting Catholicism, I'm just making what I believe to be a valid historical observation.
When Christianity first started it quickly spread, but it found its power base in Europe. A few hundred years later it was under attack by Islam and around two-thirds of the Christian population were destroyed in the Middle East. Eventually Constantinople fell (in1453) and Eastern Orthodoxy collapsed and fragmented.
Under Catholicism however, Christianity was preserved. By being under the tutelage of the Pope, Europe remained fairly united and that led to economic growth and protection from invaders. Scientific progress followed.
I believe that God preserved the Catholic Church until Europe had become the most powerful continent on Earth. Once it was stable enough, Protestantism emerged.
Europeans discover the New World and Western European nations between themselves dominated the World with their empires, The Spanish, Portuguese, French, British, Dutch, Belgians and even Germans had empires at some time or another.
Without the unifying body of the Roman Catholic Church, Christianity in Europe would have been all but destroyed and Christianity would have ended up as little more than a small, virtually unknown religion living under the bondage of Islam.
It was the British that gave the English language to the rest of the World and with it's successor the U.S.A. and with modern technology, the Bible has now been preached to all corners of the Earth.
I believe that the Catholic Church exists for a reason. Whatever you may think of it, it has had an important role to play in history and an important role in preserving the word of God.
