Unity in Community
Introduction
These verses present an ideal picture of the life of a church. The target audience (all of you) has expanded beyond husbands and wives to include everyone in the church. Harmonious living is displayed in the life of the church. Live in harmony translates a single word in the original text and means “to be like-minded.” It describes an inner unity of attitude that makes division and mutiny within the body of Christ unthinkable.
This does not mean the church will never have any differences of opinion. The variety of gifts and talents God has given his people mean differences of opinion are bound to occur. The key is not the differences; the issue is how those differences are handled. Believers should live and minister together so that the differences do not divide the church but serve to enrich its life and work. To live in harmony means Christians should pursue the same primary purpose of serving God and extending love to one another, instead of being fueled by individual and selfish interests.
This emphasis on loving one another as brothers was introduced in 1 Peter 1:22. Its repetition here suggests that practical harmony within the body of Christ will not occur without a concerted effort by individual believers to approach their relationships within the body of Christ with a familial love.
Marshall observes, “The ideal Christian community is one which produces between people who have no blood ties the same bonds of affection as are expected between brothers (and sisters)” (Marshall, 106).
