Thanks for the question.
There really is only one kind of Christian, inasmuch as Christ founded only One Church. His Church was built on the Apostles and He chose Peter to be the chief Apostle, namely what we call the Pope so there is One Church, the Catholic Church, so anyone who is Christian is in some way connected to this reality.
That being said, many people who call themselves Christian belong to Protestant churches that broke off from the One True Church. They are still Christian, though they do not have the fullness of the faith that Christ taught because they have rejected the authority of the Apostolic Church.
So in this way, there is sad division, and yet we hope to bring everyone together again through God's Mercy and the goodwill of those who love Him. To date, there are many thousands of these little Protestant churches; it is like a big family that has had too many arguments and can't stand to be in the same room with each other anymore. We pray that these wounds will be eventually healed so the whole world will be able to see the real unity that Christ intended for us.
