Methodist Blogger Morgan Guyton gives the best understanding of what Leviticus 18:22 meant and what it might mean for us today. Here’s a snippet:
In 1956, United Methodists decided that Paul’s admonition in 1 Timothy 2:12 not to “permit a woman to teach or to assume authority over a man” had an appropriate application in the early church that is no longer binding today. We decided to ordain women to the ministry, thus officially proclaiming patriarchy to be obsolete. I do not think that God’s mercy and love have been compromised by having female clergy. I have been blessed tremendously by the particular form of nurture and exhortation that female pastors can provide. Likewise, following the best Biblical interpretation I can muster, I feel that the concerns that once made homosexuality a legitimate threat to the fabric of ancient patriarchal society are no longer applicable today. I am open to being persuaded otherwise, but please give me more than a list of verses plucked out of context or an abstract argument about the nature of gender.
Read the whole thing. He makes one of the best Biblical cases in a long time, one that goes beyond the “let’s-be-inclusive” trope that too many of us too easily use.
The Clockwork Pastor 
Nearly every person who acknowledges an aversion to homosexuality does so on the basis of what he or she believes the Bible has to say. In their mind, there is no doubt whatsoever about what the Bible says and what the Bible means. Their general argument goes something like this: Homosexuality is an abomination and the homosexual is a sinner. Homosexuality is condemned in both the Old and New Testaments. Therefore, if we are to be faithful to the clear teachings of Scripture we too must condemn homosexuality. Needless to say, this premise is being widely debated among evangelicals today and seriously challenged by biblical scholars, theologians and religious leaders everywhere.
It rarely occurs to any of us that our reading of Scripture is profoundly colored by our own cultural context and worldview. In light of the post above and since I happen to speak and write on this very topic, I thought you might find some of these posts of particular interest and relevance. I would particularly recommend the following:
“Genesis 19: What Were the Real Sins of Sodom?
“Leviticus 18: What Was the Abomination?”
“Romans 1: What Was Paul Ranting About?”
“Romans 2: Paul’s Bait and Switch”
“Genesis 1: Turning the Creation Story into an Anti-Gay Treatise”
“Why No One in the Biblical World Had a Word for Homosexuality”
“Exegesis: Not For the Faint in Heart”
