The deacon's role is inherent in the name itself: "servant." Just as the title pastor means a "shepherd," one who takes care of the flock, the title deacon refers to one who serves. This does not mean that it is a lowly or unimportant office. The qualifications are quite high. They indicate that the deacon must be morally pure, spiritually mature, doctrinally strong, and able to handle money responsibly. In addition, he must be a good example in his family life and in the community.
It is not the job of the deacon to rule the church. Authority in the church comes from the Lord to the congregation. Deacons may be authorized by the congregation to serve the church in various ways, but these should be under the same headings found in Scripture. They should help the pastor with their ministry and help meet the physical and spiritual needs of the congregation.
