To Kristen (399-400)
Your argument for the difference is then that Paul’s address to the “Ephesians has an entirely different focus… he is talking about how Christians “in Christ” should relate to one another [Christian-to-Christian relationships].”
You are saying that Paul’s instructions in Ephesians to husbands and wives should actually be read as “wives submit to your husbands if they are a christian” – since you claim Paul is talking about only about christian-christian relationships.

Of course this is not what Paul actually says, and it is interesting that this is the same general instruction (‘hupotassoe’) which is offered to wives in Col 3, 1 Pet, Titus 2, etc. – regardless of the circumstances of who is being talked to.
