Okay kiddo, so you know there are different types of Christians, right? One of those types is called the Roman Catholic Church.
The Roman Catholic Church is really old and started a long time ago. It's based in Rome, which is a city in Italy. They believe in God, Jesus Christ, and the Holy Spirit, just like other Christians.
One thing that makes Catholics different is that they have a special leader called the Pope. The Pope is like the boss of the Catholic Church, and he makes important decisions about how the Church should run.
Catholics also have special ceremonies and prayers that they do, which they think help them connect with God. They go to church on Sundays and other special days to pray and listen to their priests talk about their faith.
Overall, Catholics believe in being good people and doing good things to help others. They think that by following the teachings of Jesus, they can grow closer to God and make the world a better place.
