Final answer:
Catholic Church officials that help maintain the community include Priests, Deacons, and Bishops. Bishops, especially, teach doctrine and oversee charity efforts, strengthening the church's role in society.
Step-by-step explanation:
The Catholic Church officials that help keep people in the church include Priests, Deacons, and Bishops. Priests are full-time religious leaders who administer at a local level within the church, often being responsible for a parish. Deacons assist priests in various services and administrative tasks. Finally, Bishops are responsible for overseeing a group of parishes within a diocese, and they ensure church doctrine is correctly taught and followed. The most important bishop is the Archbishop, and the archbishop of Rome is known as the Pope, the 'father' of the Catholic Church.
Regarding the question about early church hierarchy, Bishops were responsible for teaching Christian doctrine, helping the poor, and growing the church community. They played significant roles in local politics and were involved in ecumenical councils. Bishops' engagement in social services and support for the needy helped in spreading Christianity and making it a religion of compassion and aid.
