Responding to Homophobia With many thanks to Trevor and Andy for this fab resource.
In Romans 1:26-27, St. Paul talks of men and women giving up natural intercourse and being consumed with passion for each other. Is homosexuality seen as being unnatural because it is supposedly against the laws of nature or because it's against God's perfect creation? There is a danger of understanding what is natural in terms of what is customary in a given society. In some societies it is considered unnatural to wear clothes.
It is against the laws of nature for humanity to fly. It is natural that there is pain in childbirth. Paul says it is unnatural for men to have long hair (1 Corinthians 11:14), but the laws of nature dictate otherwise.
Some argue that God created male and female as a means of procreation, the sexual organs are determined by nature and their natural use must not be 'perverted'. Homosexuality is condemned because it is not procreative. Those who use this to condemn us call us to be celibate. Should women be celibate after menopause? It is dangerous to argue solely from biology when discussing God's desires for humanity.
When reading Romans 1:26-27 consider, "is there a distinction between naturally heterosexual people turning towards same sex relationships, for what ever reason, and those who are 'naturally' homosexual?"
