Pastor emphasizes leadership, care for, protection, support, correction. Teacher emphasizes communication, instruction of the Word of God. He is like both a full general and a player coach. The standard is high, but it does not indicate that spiritual leaders are more holy than anyone else. All possess sin natures, all have weaknesses, and all fail.
Deacons are leader servants for the effective performance of service.
1 Tim 3.10-13 gives qualities of deacons. The standard is high, but it does not indicate that they are more holy than anyone else. All possess sin natures, all have weaknesses, and all fail. Acts 6 illustrates the type of serving, but the men do not seem to be actual deacons. It means a servant, a helper.
