Recently finished The Bible and Homosexual Practice by Robert Gagnon, and wrote the following review on Amazon:
Gagnon provides an exhaustive defense of Scripture's proscription against homosexual sex. He makes it clear throughout that the Bible doesn't oppose the impulse to have same-sex intercourse, but the act itself. His study of Old Testament texts offers an informative look at male temple prostitutes. For a fee, they would allow themselves to be penetrated by men. They would dress like women and even castrate themselves in some cases. The men penetrating them were thought to receive a pagan blessing.
Gagnon's study of New Testament texts is equally informative. Here undercuts various attempts to silence Scripture's warnings against homosexual sex, such as Paul was only concerned with exploitive forms of homosexuality, not stable relationships. Using both biblical and pagan texts, Gagnon shows that although there were exploitive forms of homosexuality in the Ancient World, pederasty was thought to be a noble pursuit, and stable relationships between young boys and men were common. Gagnon also undercuts popular attempts to justify gay sex within the church based on the church's willingness to tolerate divorce. He clearly shows that homosexual sex is never permitted in the Bible under any circumstances, but divorce is permitted in some circumstances.
Also, Gagnon shows the health consequences for individuals and society, especially for homosexual men. Depression, AIDS, and suicidal thoughts are the risks associated with the gay population. Yet, gay activists want to make having multiple partners normative for the gay community.
Written in 2001, Gagnon was prescient with regard to the normalization of transgenderism. He also anticipated the labeling of those with a moral opposition to gay intercourse as bigots (akin to racists) and the threat to their careers. Gagnon himself has recently left his long-time professorship at Pittsburgh Theological Seminary, largely (it seems) due to the seminary's unhappiness with this biblical beliefs against homosexual practice.
Gagnon did a great service for the church in writing this book. It can not be recommended more highly.
