Why does the congregation exist? What is a congregation’s purpose. Why does a congregation need to fulfil their purpose and duties? What happens if a congregation doesn’t fulfill its purpose, or its primary tasks? Looking ahead, what kind of challenge faces the congregation in sustaining its mission/purpose?
In the business world, the terminology used for primary duties is basically referred to as corporate mission, or business plan. The terminology attempts to illuminate the business’s overall purpose, relating to the staff and its production environment. In the business world, it is important that the business plan, or mission is easy to communicate and define.
Paul writes (Romans 14:17—18), that the mission of the congregation is to represent Christ and the will of God, which is righteousness, joy and peace- all given by the Holy Spirit. A congregation devoted to its mission acts in ways that please God and serves Christ, hence these persons, its members, gain respect for one another. The righteous purpose of a congregation, can be based also on Jesus’ call to mission (Matt. 28: 19-20) the farewell prayer (Joh. 17:20-23) and Paul’s letters to the congregations (Acts 6:3-7).
From scripture we can decipher that the primary duty of a congregation consists of three areas of action:
- proclamation, kerygma (Matt. 28:19-20)
- communion, or community, Koinonia (John 14-15:7)
- service, diakonia (Ap. t. 6: 1-7, 1. Tim. 3: 8-1 3).
Proclamation in this context means sharing and teaching about the Gospel. Communion and community means that we in having a mind like Christ, would be united in our efforts, including our efforts to offer service. Service being a way to nurture and uphold those who need help meeting their needs. Paul writes, that community and communion is based closely on three shared characteristics: our sinfulness (Romans 3:23), God’s love for the sinner (Romans 5:8) and God’s salvation through grace (Titus 2:11). In contrast to missions of different communities, the congregation’s primary mission and focus always remains the same, for the person remains the same, regardless of how the times, or culture, reveal that the characteristics, opinions and habits of people are all different.
