If one claims to be Christian, he should be part of the Catholic Church

"Now, we have 1000s upon 1000s of "churches" yet they all claim to be the 'religion based on the teachings of Christ'."Yes, and they all are indeed based on the teachings of Christ. Remember that those teachings are different because they interpret different the same book. People of different beliefs inside the same religion don't agree, but they all believe they are following the same teachings.The definition of Christian is about believing one is following the teachings of Jesus Christ. There is no such a thing as a "real Christian" because there is a disagreement."Obviously the definition is speaking of Christianity as a whole, however, Christianity is divided significantly so one needs to be specific as to what church is truly of Christ. "Pro conceded with this statement. The definition is speaking of Christianity as a whole, it is speaking about all the Christians and not only about those who belong to the Catholic Church, not only about some, that like the rest, believe that they are following the same teachings of Jesus Christ. This means that Pro already accepted that they can be called Christians.And again, this is not about Church, this is not about institutions or be organized, it is about believing that Jesus Christ is the savior and believing that one is following his teachings.Pro could not say a Muslim isn't a Muslim just because you don't believe in what they believe."Therefore, a question arises, 'what Church is the Church Christ made'?"This is incorrect. There is no connection between the definitions and the question."As stated before, Christ instituted ONE Church (Matt. 16:18) and this Church is visible and not invisible. "Even if the definition of Christian was about churches, the foundation of the Church means nothing if the Church as it is now it is not like the original. What you are claiming here is that the Catholic Church should not be called a Christian religion because it is not the same as the Church founded by Christ.This is important because we are sure that the Church evolved, it changed with the world. Their beliefs and their traditions are not static.[1][2] You could say that it is because "humans changed it", but then you would concede this argument too because I would be right.I'm not here to claim things about the real teachings of Jesus. I'm using logic here. The catholic Church changed, and it not exactly like the original. Therefore, if we used your definition about the relation of Christianity and the churches, the Catholic Church should not be considered Christian. Which is false.And the last paragraphs are about why the Catholic Church was the first and original, which means nothing to the definition of Christian. The reason the rest of Christians are not following the Catholic Church is because they don't believe they are following the same teachings of the original Church as how it was the first time. They have the right to be called Christians because of the same reason Catholics have the right to be called Christian, they all believe they are following the teachings of Jesus Christ.Sources1. http://www.forbes.com...2. http://elitedaily.com...
