Christianity in the 17th century was the religion of most people living in Europe, and in many other parts of the world. It was the time of the Protestant Reformation, where some people started to question and change the way Christians practiced their faith. During this time, people went to church and believed in God, Jesus, and the Bible. They also believed that Jesus was the son of God and that he was the only way to Heaven. People in the 17th century followed the teachings of Jesus and tried to follow his example in their lives. They prayed, read the Bible, and went to church. They also attended special celebrations to honor specific Christian holidays, like Christmas and Easter.
