Commentary

KJV Study Commentary
God is faithful, by whom ye were called unto the fellowship of his Son Jesus Christ our Lord (pistos ho theos, πιστὸς ὁ θεός)—Paul grounds assurance in God's character: pistos (πιστός, "faithful, reliable, trustworthy") is the adjective form of pistis (faith). God's faithfulness guarantees our perseverance, answering the implied question: Can we endure to the end? Yes, because God is faithful, not because we are strong.

By whom ye were called unto the fellowship of his Son (di' hou eklethete eis koinonian, δι' οὗ ἐκλήθητε εἰς κοινωνίαν)—The verb kaleo (καλέω, "to call") appears again in the passive voice: God called them. Koinonia (κοινωνία, "fellowship, partnership, communion") means shared participation, not mere association. Believers are united to Christ and therefore to one another—the theological foundation for Paul's rebuke of factions in verses 10-17. How can those who share union with Christ divide over Paul, Apollos, or Cephas?

Historical & Cultural Context

Ancient Greco-Roman society was structured by patron-client relationships, voluntary associations, and philosophical schools—all of which fostered loyalty to human leaders. The Corinthians imported this culture into the church, forming competing factions. Paul redirects their loyalty: true fellowship is with Christ, mediated by God's call, not by human charisma or eloquence.

Reflection Questions

  1. How does God's faithfulness (not our performance) provide the foundation for assurance of salvation?
  2. What does it mean practically to be "called unto the fellowship of His Son"?
  3. How should union with Christ reshape our view of church unity and the sinfulness of factions?
