I’ve just come across this book by Dan O. Via and Robert A. J. Gagnon: Homosexuality and the Bible: Two Views (Fortress, 2003).
It’s a great read. Via presents the case for an open and accepting position that homosexual acts are not in themselves immoral or sinful.
Gagnon takes the traditional position that homosexual acts are sinful and that the scripture only permits monogamous heterosexual marriage or celibacy.
Each author presents their case in about 15,000 words and then each respond to each other.
Gagnon is the author of the monumental The Bible and Homosexual Practice and this essay can be seen as a revised synthesis of that book.
Key chapters that both authors examine include the usual suspects: Gen 19, Leviticus 18,20, Judges 19 Romans 1 and 1 Cor 6.
Gagnon has provided extra material on his website here.
