Reformed (Presbyterian) Lens Commentary: 1 John 1:5-10

Reformed (Presbyterian) Lens Reading of 1 John 1:5-10

Tradition-Specific Interpretation

We read 1 John 1:5-10 as an affirmation of God's transcendence and moral purity, emphasizing the absolute holiness of God ('God is light') and the pervasive need for the cleansing blood of Christ in our lives. This passage underscores the doctrine of total depravity, as it frankly acknowledges the sinfulness that remains in believers. The text calls us to live in the light, which in the context of redemptive history, means living in the forgiveness and righteousness secured by Christ's atoning work. We are reminded of our covenant relationship with God, where forgiveness and cleansing are continual graces we receive through Christ, our Mediator.

Key Language Decisions

The Greek term 'φῶς' (phōs) for 'light' is pivotal, symbolizing God's holiness and truth, contrasted with 'σκότος' (skotos), darkness, representing sin and falsehood. The phrase 'ἐὰν εἴπωμεν' (ean eipōmen, 'if we say') introduces a conditional clause, emphasizing the deceit inherent in claiming fellowship with God while walking in darkness. This tradition emphasizes the received text's insistence on the ongoing need for confession and the promise of forgiveness, aligning with our understanding of sanctification and perseverance.

Where Traditions Diverge

The Reformed tradition diverges from Arminian readings by emphasizing God's sovereign role in sanctification and ongoing forgiveness, rather than human decision or effort. Unlike some liberal theological perspectives that might downplay sin, we maintain that sin is pervasive and requires the continual cleansing found only in Christ's atoning work. This distinction matters because it grounds our assurance in God's promises rather than human performance.

Pastoral Application

As Reformed pastors, we urge our congregations to walk in the light by continually confessing their sins, assured that God is faithful and just to forgive and cleanse us. We emphasize that this forgiveness is a sovereign grace, not contingent on our merit but resting on Christ's finished work. In preaching, we should highlight the comfort and assurance found in God's unshakeable promise to preserve His people. Our congregations expect to hear about the ongoing work of sanctification as a reflection of our union with Christ, encouraging them to live out their faith in genuine fellowship with God and one another.
