Colossians 3
Paul grounds Christian ethics in resurrection reality—if then you have been raised with Christ, seek the things that are above where Christ is seated—making practical morality a consequence of positional identification with Christ's exaltation. The command to put to death earthly things (sexual immorality, impurity, passion, evil desire, covetousness) and to put off anger, wrath, malice, slander reflects a mortification ethic flowing from baptismal union with Christ. The positive clothing metaphor—put on compassion, kindness, humility, meekness, patience, bearing with one another, forgiving one another as the Lord forgave you—culminates in the command to let the peace of Christ rule in your hearts, with peace functioning as the arbiter (brabbeuō) of internal discord. Love is the binding agent (synedesmos) and perfect bond holding together all these virtues, the animating principle of the Christian community's life. The household code (wives, husbands, children, fathers, slaves, masters) is radically Christianized when Paul insists that whatever you do, do it as for the Lord Jesus, transforming even slavery into Christocentric service, since you serve the Lord Christ not merely a human master. This makes ordinary social relations arenas of gospel witness and obedience, relativizing social hierarchy under Christ's universal lordship.
Colossians 3:17
And whatever you do, in word or deed, do everything in the name of the Lord Jesus, giving thanks to God the Father through him — 'Whatever you do' (ti an poieō) is all-inclusive: every action is sacramental. 'In the name of the Lord Jesus' (en tō onomati kyriou Iēsou) grounds all conduct in Christ-authority. 'Giving thanks to God the Father through him' (eucharisteo tō Theō patri di' autou) makes gratitude Trinitarian. Life is worship; all acts are priestly.
Colossians 3:18
Wives, submit to your husbands, as is fitting in the Lord — the household code begins. 'Submit' (hypotassō) is voluntary positioning, not coercion. 'As is fitting in the Lord' (ōs anēken en kyriō) Christologically grounds submission: it fits the Lord's order. This is cultural accommodation (household codes were Greco-Roman convention) applied to Christian households. Submission is not unique but contextualized in Christ.
Colossians 3:19
Husbands, love your wives, and do not be harsh with them — husbands are commanded to 'love' (agapeō), not merely lead. 'Do not be harsh' (pikraino, embitter) forbids cruelty. The mutual command (wives submit, husbands love) establishes reciprocity: love enables submission; submission enables love. The household is not patriarchal tyranny but mutual covenant.
Colossians 3:20
Children, obey your parents in everything, for this pleases the Lord — 'Obey' (hypakouo) to parents is commanded. 'In everything' (en pasin) is comprehensive. 'For this pleases the Lord' (euarestos en kyriō) frames obedience as pleasing Christ. Parental authority reflects divine order. Yet it is qualified by 'pleasing the Lord': if parental command contradicts Christ, Christ supersedes.
