Congregations are to aspire to grow in both unity and diversity in their lives, that we might together fully express the completeness of the ministry of Christ. As individuals grow and mature in faith, the congregation will change as well. As the congregation changes together, its life has an impact of the life of each participant, encouraging them to change. The Church is a spiritual body, but it is also very much a human organization as well. It is our humanness which makes it so very hard to live up to these ideals.
Every human organization structures itself to fulfill two essential purposes.
Ford does this to make cars, hospitals do this to heal the sick, and churches do this to foster faith. IBM struggled through it's move from typewriters to laptops. The forestry industry is shifting slowly from exploitation to conservation. Hospitals try to learn how to do more with less money. Many congregations are debating the inclusion of contemporary music in their traditional worship service.
