The early church was Catholic. Not Baptist or Protestant

History tells us that there was one church for the first 1000 years of Christianity, and then that Church split into 2. The Eastern church is called Orthodox, and the western church is called Catholic. Then about 500 years later several groups broke off from the Catholic church and divided into thousands of denominations. this event, we call the Protestant Reformation, and the church lost about a 3rd of Europe. Every Christian group that exists today, other than the Orthodox and Catholic churches, comes from the Protestant Reformation. This is an historical fact.

However, some very fundamental Protestants deny this fact. They say that they were the original church. And that their structure, worship styles and beliefs were the original. And that in the 4th century the Emperor Constantine instituted Roman Catholicism, driving the true church underground. mixing Roman paganism in with the true faith resulting in the various catholic beliefs that differ from their beliefs.
