Our church has recently been discussing the biblical teachings on sexuality, marriage, divorce, and remarriage. This is, of course, an astoundingly difficult subject both practically and morally, as well as exegetically and hermeneutically. The deeper into the issue you go, the more levels of complexity and confusion you find, and more differences of opinion between loved and respected pastors and teachers.
In that vein, you might be interested in this online conversation happening between two theologians from whom I’ve benefited greatly over the past few years—Doug Wilson, and Dominic Tenant. It concerns some of the finer/stickier points of when a wife may be allowed, biblically, to leave her husband.
It started with Pastor Wilson’s fictional letter to a wife considering leaving her husband over abuse and mistreatment.
Wilson has a fairly loose interpretation of Paul’s instruction in 1 Corinthians 7, so Dominic Tennant offered a few critiques of Wilson’s exegesis here.
