Last April, I spoke on a panel representing Wheaton College. We were in a discussion with Soulforce (Equality Ride) on the topic of homosexuality. I stand with Soulforce in denouncing violence/discrimination toward any human being, "gay" or "straight." However their view of homosexuality is not based upon Scripture. To their detriment, Soulforce intentionally avoided all discussions regarding the biblical perspective of homosexuality. Instead they focused upon an issue on which we all agreed (i.e. the injustice of violence and discrimination) and didn't provide any reason to change our stance that God desires for all of us to be transformed through the redemption of Jesus Christ.
This Spring, Soulforce plans to visit 40 schools and military institutions. Last year they visited 20 schools in one bus. This year they plan to take two buses taking two different routes.
Here is a good resource from Dr. Stanton L. Jones, Ph.D., Provost of Wheaton College, "A Study Guide and Response to: Mel White's What the Bible Says and Doesn't Say About Homosexuality." It is a 43 page pdf document which includes Mel White's booklet.

Another response is from Dr. Daniel B. Wallace who is considered an authority on Biblical Greek grammar and New Testament textual criticism. Two-thirds of schools that teach Biblical Greek use his textbook which is the standard work in the field.
