During the Greco-Roman period that this passage was written, women had no rights at all. Peter is actually elevating the view of women by the mere fact he is writing directly to them. No rabbi would do that then. His call for them to submit to their husbands was not to subjugate them but to avoid upsetting the entire social and economic system. By flaunting their new-found rights, they needlessly risked alienating all unsaved men. Peter calls women instead to win their unbelieving husbands to Christ by their exemplary behavior. Believing husbands are also called to show honor to their wives.
