Should there be a diaconate in a church? First of all we need to know what a diaconate is. It is a group of church members who have been appointed as deacons in a church who meet together to discuss and decide corporately, on issues related to church business. Let us consider this issue.
It is clear from scripture that there should be deacons in a church. At Philippi for example. Paul and Timothy writes To all God’s holy people in Christ Jesus at Philippi, together with the overseers and deacons: (Phil 1:1). In Acts 6 with those appointed to resolve the issues of the dispute of allocation of resources among the widows we appear to have the prototype deacons established. These are men who take on a responsibility for practical church matters so as to allow the elders to function in their shepherding role.
The Acts 6 passage is most helpful in guiding us to the conclusion that deacons are appointed to serve in certain responsibilities. So deacons should not just be generically appointed to be deacons. Rather they should be appointed to certain tasks. So you have a deacon responsible for the buildings or responsible for the finances or responsible for stewarding or responsible for music etc.. The key thing is that they are taking on the supervising of tasks so as to release the elders for their leading ministry.
It is the elders who are to meet together to discuss and decide corporately on issues related to church business. Which all means that there should not be a diaconate in a church. Deacons serve certain ministries (generally of a practical nature), they are not a collective decision making body in a church.
