Whenever I (Dr. Townsend) talk about a wife setting boundaries in marriage, someone asks about the biblical idea of submission. What follows is not a full treatise on submission, but some general issues you should keep in mind.
First, both husbands and wives are supposed to practice submission, not just wives. "Submit to one another out of reverence for Christ" (see Ephesians 5:21). Submission is always the free choice of one party to another. Wives choose to submit to their husbands, and husbands choose to submit to their wives.
Christ's relationship with the church is a picture of how a husband and wife should relate: "Now as the church submits to Christ, so also wives should submit to their husbands in everything. Husbands, love your wives, just as Christ loved the church and gave himself up for her to make her holy, cleansing her by the washing with water through the word, and to present her to himself as a radiant church, without stain or wrinkle or any other blemish, but holy and blameless" (see Ephesians 5:24-27).
Whenever submission issues are raised, the first question that needs to be asked is, What is the nature of the marital relationship? Is the husband's relationship with his wife similar to Christ's relationship with the church? Does she have free choice, or is she a slave "under the law"? Many marital problems arise when a husband tries to keep his wife "under the law," and she feels all the emotions the Bible promises the law will bring: wrath, guilt, insecurity, and alienation (see Romans 4:15; Galatians 5:4).
Freedom is one issue that needs to be examined; grace is another. Is the husband's relationship with his wife full of grace and unconditional love? Is she in a position of "no condemnation" as the church is (see Romans 8:1), or does her husband fail to "wash her" of all guilt? Usually husbands who quote Ephesians 5 turn their wives into slaves and condemn them for not submitting. If she incurs wrath or condemnation for not submitting, she and her husband do not have a grace-filled Christian marriage; they have a marriage "under the law."
Often, in these situations, the husband is trying to get his wife to do something that either is hurtful or takes away her will. Both of these actions are sins against himself. "Husbands ought to love their wives as their own bodies. He who loves his wife loves himself. After all, no one ever hated his own body, but he feeds and cares for it, just as Christ does the church" (see Ephesians 5:28-29).
Given this, the idea of slave-like submission is impossible to hold. Christ never takes away our will or asks us to do something hurtful. He never pushes us past our limits. He never uses us as objects. Christ "gave himself up" for us. He takes care of us as he would his own body.
I have never seen a "submission problem" that did not have a controlling husband at its root. When the wife begins to set clear boundaries in marriage, the lack of Christlikeness in a controlling husband becomes evident because the wife is no longer enabling his immature behavior. She is confronting the truth and setting biblical limits on hurtful behavior. Often, when the wife sets boundaries, the husband begins to grow up.
