Lutheran Lens Commentary: 1 John 4:17-21
Lutheran Lens Reading of 1 John 4:17-21
Tradition-Specific Interpretation
We read 1 John 4:17-21 through the lens of Law and Gospel, emphasizing God's perfect love revealed in Christ as the Gospel promise that casts out fear. The passage underscores our inability to love perfectly (Law) and the assurance of our standing before God through Christ's love (Gospel). The text also highlights our baptismal identity in Christ, where love for one another flows as a fruit of faith, not as a condition of God's love. Theologically, we see this as an exposition of the simulative nature of the believer — simul justus et peccator — fully righteous in Christ yet struggling with the old Adam.
Key Language Decisions
In the Greek, the term 'teleioo' (perfected) in verse 17 is critical. It indicates a completion in God's love that we receive in Christ, not achieved by our efforts. Verse 18's 'phobos' (fear) conveys the existential dread of judgment, which the Gospel alone removes. Our tradition emphasizes the received text's focus on God's active love in Christ, not on human attempts to fulfill the Law.
Where Traditions Diverge
Unlike the Reformed tradition, which may emphasize love as evidence of election, we focus on love as fruit of faith grounded in justification. Catholic readings might stress love as cooperative grace, while we uphold justification by faith alone as the source of our love. These differences matter because they shape how we understand assurance and Christian identity.
Pastoral Application
A Lutheran Lens pastor should reassure the congregation that God's love in Christ drives out all fear of judgment, grounding their assurance not in their love but in Christ’s perfect love. The sermon should highlight our baptismal identity, calling believers to love others as a response to the Gospel, not a prerequisite for it. We emphasize that love for one another is a vocation that flows from being justified by faith alone, reminding the congregation that they are simul justus et peccator, fully loved and forgiven in Christ even as they struggle with sin.
Cross-References: Romans 8:15 (spirit of adoption, not fear); John 15:12-13 (command to love one another); Ephesians 2:8-9 (saved by grace through faith); Galatians 5:6 (faith working through love)
