Pastors
In the Bible, we see churches that are lead by local pastors.
In the book of Acts, we see words like bishop, pastor, elder, shepherd and overseer all used interchangeably in addressing the same group of people. These are team that are ordained to take care of the affairs of the church. This is a broad description and each persons specific role and responsibilities are determined by the areas of the church they actively oversee and the teams they work with in doing so.
Deacons
In the Bible, we see the appointment of deacons in Acts chapter 6.
They are leaders, selected from within the local church to work along side and assist the pastors in taking care of the needs of the church. These could be practical or spiritual needs. Deacons carry responsibility for the people in the church not just the practicalities of the church. An effective deacon team releases the pastors to focus on their specific roles and empowers the church to grow well beyond the capacity of any of it’s individual leaders.
