What This Chapter Is About
Ephesians 6 completes the household code with instructions for children and parents, then slaves and masters. The chapter's climax is the armor of God passage (vv. 10-20), one of the most vivid and beloved sections in Paul's letters. Paul identifies the true battle — not against flesh and blood but against cosmic spiritual forces — and equips believers with divine armor: the belt of truth, the breastplate of righteousness, the shoes of the gospel of peace, the shield of faith, the helmet of salvation, and the sword of the Spirit. The chapter closes with personal notes about Tychicus and a final benediction.
What Makes This Chapter Remarkable
The armor of God passage draws on Isaiah's description of God's own armor (Isaiah 59:17; 11:5) — believers wear God's equipment, not their own. The list of spiritual enemies (v. 12) is the fullest taxonomy of evil powers in the New Testament. The only offensive weapon in the armor is 'the sword of the Spirit, which is the word of God' (v. 17). Prayer (vv. 18-20) is not a separate piece of armor but the atmosphere in which all the armor functions. Paul's request for prayer that he might speak boldly 'in chains' (v. 20) is poignant — the ambassador is in prison.
Translation Friction
The slave-master instructions (vv. 5-9) operate within the institution of slavery without explicitly condemning it. Paul subverts slavery from within (masters and slaves have the same Master in heaven, v. 9) but does not call for abolition. The spiritual warfare language (vv. 10-20) raises questions about how literally to read the cosmic powers. We render the text as given without either literalizing or demythologizing.
Connections
The children/parents instruction parallels Colossians 3:20-21. The slave/master code parallels Colossians 3:22-4:1 and Philemon. The armor imagery draws on Isaiah 59:17 and 11:5, and parallels 1 Thessalonians 5:8 and Romans 13:12. Tychicus also appears in Colossians 4:7-8, Acts 20:4, 2 Timothy 4:12, and Titus 3:12.
