What Is the Role of a Deacon?
The basic meaning of Greek word group behind the English translation "deacon" (diakon-) suggests the notion of service and servanthood (John 2:5; Romans 15:8; Matthew 20:26; Luke 10:40; Acts 11:29; 12:25), especially in regard to providing practical help with respect to the basic necessities of life (Matthew 4:11; 8:15; 27:55; Luke 10:40; Romans 15;25). The basic task of deacons, then, seems to be helping those in need of food, water, and clothing, as well as ministering through hospitality and welcoming.
