Church membership is the committed relationship between a believer and a local congregation.
While the New Testament does not present membership through modern administrative procedures, it consistently assumes identifiable congregations whose members worship, serve, submit to spiritual leadership, and care for one another.
Membership reflects the biblical reality that Christianity is not intended to be lived in isolation. Believers are called into fellowship with God's people and are expected to participate in the life, mission, worship, and accountability of the local church.
See in Scripture: Acts 2:41–47; Romans 12:4–5; 1 Corinthians 12:12–27; Hebrews 10:24–25; Hebrews 13:17
