Bad theology in service to a good cause?

Over at Ref21 Rick Phillips posted a vigorous defense of complementarianism. I agree with much of his defense. What was particularly encouraging for me however was his clear statement regarding ESS. 

Recent months have seen considerable controversy among conservative Christians around the topic of complementarianism, arising mainly from a false analogy between the subordination of wives to husbands and that of God the Son to God the Father. Depending on your perspective, the complementarian view has been either maligned, discredited, or reformed. My hope is that events will prove that the latter has taken place. I am in complete solidarity with those who reject the eternal subordination of the Son in any form, since no amount of nuance or affirmation of Christ's deity can preserve it from functionally reproducing the Arian position. There are no ends for which a degrading of the Trinity is an excusable means. I am therefore grateful for the way this controversy, though regrettably contentious, has highlighted massively important issues of theology that tend to receive little attention. At the same time, my hope is that this attempt to reform the complementarian position will not truly damage the important stand it takes.  (emphasis mine)

I appreciate Rev. Phillips' clarity on this point. Here at MOS we have expressed deep concern over the fact that CBMW has anchored the Bible's teaching on the roles of men and women in the church and family to ESS. I continue to hope that CBMW will once and for all refute ESS. Tethering the Bible's teachings on the relationships within the church and family to error about the Trinity is proving to be disastrous. We must never seek to advance truth through means of error.
