So much of this conversation is predicated in modern, western culture. Our jobs are harder. We wouldn't be having to hone our leadership skills at home, only on the battlefield, if we lived 1000 years ago, or even less. It was assumed that the father and husband were the absolute authority at home and the wife tried to figure out ways to circumvent that, not the other way around.Following on that, when the pastor says, "Submission must be voluntary. You can't force her to do anything. You need to convince her to want to follow you. Scripture doesn't allow you to tell her she must obey you." he is arguing you have no authority over her, your authority to act only comes from her. He's arguing she is your head. Which is why these types usually find abhorrent the thought of a husband enacting consequences for disobedience.
It sounds true, since we can't physically force her to obey; she still has free will. But the statements are predicated upon the fact of her headship over you. Free will to act contrary to authority doesn't mean authority doesn't exist. If it did, we wouldn't have a word for rebellion.
In other words, I mostly agree with you, brother.
