445. Did other ministries proceed from the Apostle ministry?

Yes. The Apostles and other believers established new congregations, and new ministers were needed to provide them with pastoral care. For this the Apostles ordained congregational leaders who were designated as “Bishops” or “Elders”. Prophets, evangelists, pastors, and teachers were also active in the beginnings of the Christian congregations (cf. Ephesians 4: 11).
