Christianity is a religion that people have been following for hundreds of years. In the 20th century, people around the world continued to follow the teachings of Jesus Christ, the founder of Christianity. Churches, organizations and schools were established to teach people about the religion, and many people began to talk about it in different ways. There was also a rise of Protestant churches, which emphasize a personal relationship with God. During the 20th century, Christianity also moved away from being very strict and formal, and people began to find new and more modern ways to practice the faith.
