Romans 1:27 - And likewise also the men, leaving the natural use of the woman, burned in their lust one toward another; men with men working that which is unseemly, and receiving in themselves that recompense of their error which was meet.
Chapter 1 of Paul's letter to the Roman Christians cites several of the most egregious sins of the people who lived prior to the flood, and cited homosexual acts performed by both men and women as one of the most offensive to God's holiness. I would think that a man who claims to be called by God to proclaim the Gospel of Christ would know that as well as a layman like myself.
That does not remove the fact that the Leviticus reference is inapt. Different audience. Some people address the phenomenon, not with the focused anger of God that would deliver if at all possible, but with the rage of man that tries to heap up any straw of condemnation to get it out of his hair.
