Ephesians 4
Having established the theological indicative, Paul now shifts to the ethical imperative: believers are called to walk worthy of their calling with humility, gentleness, patience, and forbearance in love, preserving the unity of the Spirit in the bond of peace. The foundation for this worthy conduct is christological and pneumatological: one body animated by one Spirit, one hope, one Lord, one faith, one baptism, one God and Father of all who is over all and through all and in all—a sevenfold unity that reflects and participates in the Trinitarian life. The ascended Christ distributes gifts to the church (citing Psalm 68:18 in its christological interpretation): apostles, prophets, evangelists, shepherds and teachers equip the saints for ministry, building up Christ's body until all attain to the unity of faith and the knowledge of the Son of God, growing up into Christ the head (kephalē), from whom the whole body is joined and knit together. The command to speak truth in love (alētheia in agapē) implies a transformation where falsehood, anger, corrupt speech, and grieving of the Holy Spirit—in whom they were sealed for the day of redemption—give way to kindness, tenderness, and forgiveness rooted in God's forgiveness in Christ. These specific imperatives form the pattern of the new humanity: let no lie pass the lips, resolve anger before sunset, speak only words that build up and give grace, refuse all bitterness and malice, and instead embody the compassion and mutual forgiveness that mirrors Christ's reconciling work.
