My view currently is that texts like I Peter 3 seem pretty straight-forward, and do indicate wives submit to husbands. Though it also warns husbands to treat wives honorably.
There appears to be no situation unique to a given area, because he addresses churches in various Roman provinces:
1 Peter 1:1 1 Peter, an apostle of Jesus Christ, To the pilgrims of the Dispersion in Pontus, Galatia, Cappadocia, Asia, and Bithynia,
He ties it to holy women of the past, taking it beyond the local situation:
1 Peter 3:5 For in this manner, in former times, the holy women who trusted in God also adorned themselves, being submissive to their own husbands
He references a specific OT passage for support:
1 Peter 3:6 6 as Sarah obeyed Abraham, calling him lord. And you are her children, if you do good and do not fear anything that is frightening.
Genesis 18:12 . 12 Therefore Sarah laughed within herself, saying, “After I have grown old, shall I have pleasure, my lord being old also?” (NKJV)
Peter references cautions to men against treating wives poorly, and assures that women are co-heirs of salvation:
1 Peter 3:7 Likewise, husbands, live with your wives in an understanding way, showing honor to the woman as the weaker vessel, since they are heirs with you of the grace of life, so that your prayers may not be hindered.
Peter was married, as we see reference to his mother-in-law, and Paul's statement about him having a believing wife. So while some have at times indicated Paul's view may be shaped by his unmarried state, the same would not be true of Peter.
Matthew 8:14 And when Jesus entered Peter’s house, he saw his mother-in-law lying sick with a fever.
1 Corinthians 9:5 5 Do we have no right to take along a believing wife, as do also the other apostles, the brothers of the Lord, and Cephas?
The passage shows continuity between the behavior of holy women of old, and those in the New Testament era, in a variety of locations.
In its cautions regarding treatment of wives it also parallels Ephesians 5.
In its relating that wives are co-heirs of the grace of life it parallels Galatians 3, where there is no male or female in Christ in regards to being heirs of the promise.
