What is the context?
The readers have known the command from the beginning, yet its reality in Christ and among them makes it fresh. The fading darkness and shining light describe the setting in which love becomes visible.
The test again reaches past a spoken claim. Hatred of a brother contradicts life in the light and blinds the person’s way. Love is not an optional extra added to correct statements about God.
How is this passage commonly understood?
Wesley understands the command as old in its earlier giving and new in its expression through Christ and His people. The USCCB notes likewise emphasize continuity and freshness. The letter names brotherly love as the practical question, rather than requiring a speculative reconstruction of its opponents’ entire philosophy.
Where does this fit in God's plan?
In John 13:34–35, Jesus gives the new command to love one another as He has loved His disciples, making that love their public identifying mark. This direct parallel explains the command’s Christ-centered measure: His own love shapes the life His followers share.
