The founder of Christianity is either Jesus Christ or the apostle Paul, depending on which side of the debate one takes. Jesus created the teachings of the Gospel, but Paul implemented them throughout the ancient world, spreading a religion that may have originally been meant as a new Judaism.
While the first four books of the New Testament of the Bible are focused on the life and teachings of Christ, the later books are written by several apostles. The most notable of these apostles is Paul, who is credited with writing 14 out of the 27 books of the New Testament. He used his wealth and status as a Roman citizen to found churches throughout Asia Minor and Europe, creating a wide base to stand as the foundation of the Christian Church.
