Okay kiddo, so the Coptic Orthodox Church is a group of people who believe in Jesus and follow a special way of praying and living their lives. They are split up into different groups, called dioceses, kind of like how your classroom is split up into different groups with your teacher.
Each diocese in the Coptic Orthodox Church has a special leader who is like a boss. They are called bishops. They are responsible for making sure everyone in their diocese is following the right rules and praying the right way. They help teach people about Jesus and make sure they are growing in their faith.
Dioceses can also have different churches in them, kind of like how you can have different classrooms in your school. Each church has a special priest who helps lead the people in prayer and helps them grow in their faith.
So, just like how your teacher and principal help make sure everything runs smoothly in your classroom and school, the bishops and priests in the dioceses of the Coptic Orthodox Church help make sure everything runs smoothly in their group of people who believe in Jesus.
