The image of God is both male and female and is reflected in a godly union between male and female where the creative power of God, His life-giving, His self-giving and His moral nature are perfectly expressed. This is only possible in a heterosexual union.
When God created a partner for Adam He created Eve—not another Adam. This means that perfect partnership requires some level of difference as well as a level of similarity so great that Adam could cry out loudly, ”This is now bone of my bones and flesh of my flesh”. Sexual intimacy between a man and a woman is the normal method of male/female bonding (emotionally and physically) because it corresponds to the design of our bodies and because it is the normal means by which offspring are created.
If God had intended the human race to be fulfilled through both heterosexual and homosexual marriage, He would have designed our bodies to allow reproduction through both means and made both means of sexual intercourse healthy and natural. Homosexual *bleep* intercourse carries a high risk of disease, this is recognized in Scripture where gay men are said to receive in their bodies the due penalty for their error (Romans 1:27).
[Editor’s Note: Various studies indicate that homosexual behavior makes both men and women more vulnerable to disease and decreases lifespan. See: R.S. Hogg, S.A. Strathdee, KJ Craib, M.V. O’Shaughnessy, J.S. Montaner and M.T. Schechter, “Modelling the impact of HIV disease on mortality in gay and bisexual men,” International Journal of Epidemiology, Vol. 26 (Oxford University, 1997), pp. 657-661. (“If the same pattern of mortality were to continue, we estimate that nearly half of gay and bisexual men currently aged 20 years will not reach their 65th birthday”) / Executive Summary, “Health Implications Associated with Homosexuality,” Medical Institute of Sexual Health (1999) (”Homosexual men are at significantly increased risk for HIV/AIDS, hepatitis, *bleep* cancer, gonorrhea and gastrointestinal infections.” “Women who have sex with women are at significantly increased risk of bacterial vaginosis, breast cancer and ovarian cancer than are heterosexual women.”) / L.A.

(demonstrates that high risk behaviors are still quite common among homosexual men).]
