a joint sharing in something held in common: having a real stake in the same thing, and the bond that creates
At its root this word is about a share, not a feeling. It names what happens when two or more people genuinely hold one thing in common: they both have a stake in it, and that shared stake binds them together. Everyday Greek used it for a marriage, a business partnership, or a treaty, where two parties pool what they have toward one end.
The New Testament takes that ordinary word and stretches it to name the deepest reality it knows: that believers actually share in Christ himself, in his Spirit, in his sufferings, even in the life of God. From there it also names the community that this shared stake creates, the closeness Christians have with God and with one another. And it stays concrete enough to mean a money gift, because handing over your resources is one literal way of sharing what you have.
These are not three unrelated words but one idea seen from different angles. The thread running through all of them is a thing held jointly: when the thing shared is Christ or his Spirit, it reads as participation; when the focus falls on the people drawn together, it reads as fellowship; when the focus falls on pooled resources, it reads as a contribution. The same act of sharing carries all three at once, which is why no single English word quite holds it.
Nuances
How real is the share in Christ's blood and body in the cup and the bread at 1 Corinthians 10:16: a genuine participation, or only a symbol or memorial?
- majorityA real, not merely symbolic, share in Christ, parallel to how eating sacrifices makes one a partner of the altar (verse 18) and eating pagan sacrifices makes one a partner of demons (verse 20); confessions still differ on how thick that participation is.; Anthony C. Thiselton, The First Epistle to the Corinthians, NIGTC (Grand Rapids: Eerdmans, 2000), pp. 755-771; Richard B. Hays, First Corinthians, Interpretation (Louisville: John Knox, 1997), pp. 167-169; Gordon D. Fee, The First Epistle to the Corinthians, NICNT (Grand Rapids: Eerdmans, 1987), pp. 466-469
- minorityA symbol or memorial of Christ's death rather than a real share in him; this older reading has largely receded from technical scholarship.
