1 Peter 3 is a tricky passage. It’s often been twisted to pressure abused women to stay with their husbands as a sign of submission. But this passage is not meant to subject women to fear or violence; it is supposed to encourage primary loyalty to Christ, not to husbands.
There are several passages in the New Testament that list the spiritual gifts believers receive for the purpose of building up of the body of Christ (1 Corinthians 12; Romans 12; Ephesians 4; 1 Peter 4). Much has been written about these lists and their implications, particularly for how we ought to recognize and understand spiritual gifts in the church.
Peter states what should be common sense: husbands, live with your wives in a considerate and respectful manner. He then goes on to say that if a husband does not do this, his relationship with God will suffer.
When I have heard discussion about love and respect it is often applied as gender specific: a woman needs love, a man needs respect. But it isn’t that cut and dry. Men need to be loved as well, and women need to be respected, too.
