Someone asked me why these people like the Theobros make everything so weird. Well, let's break it down. We've used good hermeneutics to study good theology. Now, you'll hear some spermeneutics to learn about Spread Your Legs Theology. (Shirley Taylor gets credit for naming this theology. It's like a sanitized version of the Kinder, Küche, and Kirche, but it's remade to be Biblical for Christians.)
People wanted to keep women in their place to save the family. In the late 1970s, George Knight III came up with the idea that relationships in the family corresponded to the Divine Persons in the Trinity (as they prefer a social view of the Trinity with an emphasis on three Personalities). During his teaching ministry, RC Sproul taught that all orthodox doctrine finds its roots in the Doctrine of God and proceeds from it, and it shaped the ideas of the New Calvinists. It was not just enough that the New Testament passages that concern gender specified to these men that women should be subordinate to men, so they came up with a new, more robust argument that tipped the balance of power to favor men by changing the Protestant Doctrine of the Trinity.They demoted Jesus to the model for women (even though He was the only Divine Person with a body that was male). Hence, women became the eternally suffering servants for their men. Bruce Ware redefined women as the “indirect image of God” or a derivative of man, defining women as the ontological lesser of men. They changed their theology to make women a little less human or perhaps not as fully human as a man. So a man in marriage gets to rule and reign over his woman like God the Father rules and reigns over the Son. Wayne Grudem wrote a theology text claiming this as legitimate, traditional doctrine, and it's now the most commonly used English text used to train pastors.
We women are not fully human. How do you have intimacy with an object or a lesser creature? Sex cannot be a union of souls if this is the case. Sex becomes a purely physical act.
Well, it doesn't surprise me then that the men who came up with and defend this doctrine cooked up other bells and whistles to embellish what sounds much less like the celebration of the communion of two souls through the pleasure of sex into something else. There is also what I've heard Pia Mellody teach about caretakers in relationships. It doesn't happen to everyone, but when one person draws worth from another in that situation, it kills intimacy because it's not truly a reciprocal relationship if the person being cared for becomes objectified. Drama replaces intimacy, and love becomes duty with a sense of deadness.
So how do you revive your dead orthodoxy? You come up with theological innovations to try to inject new life into that dead orthodoxy. You have to do something to make lemonade out of all those lemons. Tim Keller, Frank Viola, Doug Wilson, David Bayly, Mark Driscoll, and others have turned sex into either "velvet-gloved violence" of swordplay or an orgy about and with the Trinity. The Evangelical erotica writes itself. Sex is all about them and for them.
