CONTRIBUTION 

kon-tri-bu’-shun (koinonia, “communion” or “fellowship,” Romans 15:26, 2 Corinthians 9:13): The meaning “contribution” is drawn from the context, rather than from the Greek word. The phrase in the passage cited, literally rendered, would be “to exercise” or “put fellowship into activity.” The koinonia subsisting among believers because of their inner communion with Christ places them and their gifts and possessions at the service of one another (see COMMUNION). They are enjoined to not forget to communicate (Hebrews 13:16). To be “communicative” (koinonikoi) is to be a habit of their lives, the Christian principle being that of the holding of all property as a trust, to be distributed as there is need (Acts 2:44, 2 Corinthians 8:14). The first occasion for calling this fellowship into activity, by way of “contributions,” was within the church at Jerusalem and for its needy members (see COMMUNITY OF GOODS). The second occasion was repeated from the infant Gentile churches for the poor within the same church (Acts 11:29, Romans 15:26, 2 Corinthians 8:1-4, 2 Corinthians 9:2); the fellowship thus widening from intra-congregational to general church benevolence. These contributions were gathered weekly (1 Corinthians 16:2), were proportioned to the means of the givers (Acts 11:29, 1 Corinthians 16:2), were not exacted or prescribed in a legalistic manner, but were called forth as the free-will offerings of grateful hearts 

(2 Corinthians 8:7), springing from the community spirit, and were sent to their destination by accredited representatives of the congregations 

(1 Corinthians 16:3, Acts 11:30). 

Agree or disagree with the above?

Scripture clearly challenges us in the area of possessions and community. The term “communion of saints,” found in the ancient “Apostle’s Creed” makes reference to this concept as well. Because of the permanence of our relationship to God the Father through the Son, and in the Spirit, Scripture makes a strong case for our familial connection and responsibility to other believers. How do these concepts challenge you personally?

Let’s close our study of koinonia with the only place in Scripture where the word is used to describe “Communion” (Lord’s Supper). “Is not the cup of thanksgiving for which we give thanks a participation in the blood of Christ? And is not the bread that we break a participation in the body of Christ? Because there is one loaf, we, who are many, are one body, for we all share the one loaf” (1 Corinthians 10:16-17).

With this week’s study of koinonia, how does this passage change your view of the Lord’s Supper?
