This blog post articulates a view of research (and message to Evangelicals) from a theologian that is not far from my own. This is a significant statement from a very prominent Evangelical.
Dr. Mohler ends with this observation:
Christians must be very careful not to claim that science can never prove a biological basis for sexual orientation. We can and must insist that no scientific finding can change the basic sinfulness of all homosexual behavior. The general trend of the research points to at least some biological factors behind sexual attraction, gender identity, and sexual orientation. This does not alter God’s moral verdict on homosexual sin (or heterosexual sin, for that matter), but it does hold some promise that a deeper knowledge of homosexuality and its cause will allow for more effective ministries to those who struggle with this particular pattern of temptation. If such knowledge should ever be discovered, we should embrace it and use it for the greater good of humanity and for the greater glory of God.
I understand that some regular readers will take exception to his theological view of homoeroticism. My point here is to note that a major Evangelical leader has acknowledged the potential role of prenatal factors for some homosexuality which seems to be at odds with the prevailing view the U.S..
