What does koinonia mean?

Redemption Theology

TL;DR:

Koinonia is fellowship, involving both relationship and shared action with God and other believers. True koinonia shapes us through the work of Christ found in community.

Koinonia, meaning fellowship, is both a relationship with God and active participation in His work alongside other believers. In the Old Testament, God called His people into covenant fellowship, seen in His promises to Abraham, the Sinai covenant with Israel, and the communal life of His people. Festivals, sacrifices, shared resources, and care for the poor fostered mutual responsibility and participation in God’s holiness. In the New Testament, koinonia is central to the church, involving communion with God, unity with the Holy Spirit, devotion to teaching, prayer, generosity, and even sharing in Christ’s sufferings. True fellowship is inherently active. It requires our engagement and participation. It is not one-way though; it shapes our character, guides our actions, and unites us in purposeful engagement. Believers are called to cultivate koinonia with other Christians while avoiding associations that compromise holiness. Through koinonia, we grow in faith, recognizing that it is not meant to be lived alone.

from the old testament

God called His people into covenant fellowship. The covenant with Abraham (Genesis 12:1–3; 15:1–6), the covenant at Sinai with Moses and Israel (Exodus 19:5–6; 24:3–8), and the ongoing life of Israel as God’s chosen people all demonstrate that being part of God’s people meant sharing in His promises, laws, and blessings.
Israel was instructed to live in ways that promoted mutual care, justice, and support. Practices such as celebrating festivals (Leviticus 23), offering sacrifices (Leviticus 1–7), sharing resources (Leviticus 19:9–10), and helping the poor (Deuteronomy 15:7–11) reflect early forms of communal fellowship and interdependence.
The sacrificial system (Leviticus 1–7), priestly roles (Numbers 3:5–10), and temple worship (1 Kings 8:22–61) provided avenues for Israel to participate in God’s holiness and presence, which foreshadows the New Testament truth that koinonia involves active sharing in God’s work and presence.

from the new testament

The concept of koinonia is an important one because it is supposed to characterize the church. John says that the purpose of the Gospel is to lead people to have koinonia with others and with God (1 John 1:3, 6-7).
Several verses exhort us to have koinonia with the Holy Spirit (2 Corinthians 13:14; Philippians 2:1).
Acts 2:42 (NASB) reflects koinonia in the very young church, "They were continually devoting themselves to the apostles' teaching and to fellowship, to the breaking of bread and to prayer."
Koinonia refers to more than the warm feeling of relationship. In Romans 15:26, which lists churches that have made a contribution to the poor in Jerusalem, "contribution" is the word koinonia.
First Corinthians 10:16 says that communion is koinonia.
Philippians 1:5 says we are to have an active koinonia with the Gospel.
Philippians 3:10 tells us to have fellowship even with Christ's sufferings.

implications for today

Although the word koinonia is a noun, the natural result of koinonia is inherent in its existence. That's something we should remember: there is no fellowship without action. Our actions are widely influenced by our associations. Fellowship is both the unity of the group and whatever is brought forth out of that association.

For this reason, we are to be careful with whom we have fellowship. Second Corinthians 6:14 says "Do not be unequally yoked with unbelievers. For what partnership has righteousness with lawlessness? Or what fellowship has light with darkness?" Our associations direct our actions, and to be bound with unbelievers will inevitably lead to wrong actions. To have koinonia with God and other believers, however, is to find our place in the body and the work of Christ.
