Homosexual activists have claimed that sexual orientation cannot be changed. What if a hormone patch during pregnancy will do the job?

As Gray suggests:

In a culture that encourages us to customize everything from our Nikes to our venti skinny lattes, perhaps it is only a matter of time before baby-making becomes just another consumer transaction. Already have a girl? Make this one a boy! Want to impress your boho friends? Make a real statement with lesbian twins!

More to the point, Gray understands that such a development would reshape the abortion and gay-rights debates in America:

Conservatives opposed to both abortion and homosexuality will have to ask themselves whether the public shame of having a gay child outweighs the private sin of terminating a pregnancy (assuming the stigma on homosexuality survives the scientific refutation of the Right's treasured belief that it is a "lifestyle choice.") Pro-choice activists won't be spared either. Will liberal moms who love their hairdressers be as tolerant when faced with the prospect of raising a little stylist of their own? And exactly how pro-choice will liberal abortion-rights activists be when thousands of potential parents are choosing to filter homosexuality right out of the gene pool?

The development of Preimplantation Genetic Diagnosis [PDG] is one of the greatest threats to human dignity in our times. These tests are already leading to the abortion of fetuses identified as carrying unwanted genetic markers. The tests can now check for more than 1,300 different chromosomal abnormalities or patterns. With DNA analysis, the genetic factors could be identified right down to hair and eye color and other traits. The logic is all too simple. If you don't like what you see on the PDG report . . . just abort and start over. Soon, genetic treatments may allow for changing the profile. Welcome to the world of designer babies.

If that happens, how many parents -- even among those who consider themselves most liberal -- would choose a gay child? How many parents, armed with this diagnosis, would use the patch and change the orientation?

Christians who are committed to think in genuinely Christian terms should think carefully about these points:

1. There is, as of now, no incontrovertible or widely accepted proof that any biological basis for sexual orientation exists.

2. Nevertheless, the direction of the research points in this direction. Research into the sexual orientation of sheep and other animals, as well as human studies, points to some level of biological causation for sexual orientation in at least some individuals.

3. Given the consequences of the Fall and the effects of human sin, we should not be surprised that such a causation or link is found. After all, the human genetic structure, along with every other aspect of creation, shows the pernicious effects of the Fall and of God's judgment.

4. The biblical condemnation of all homosexual behaviors would not be compromised or mitigated in the least by such a discovery. The discovery of a biological factor would not change the Bible's moral verdict on homosexual behavior.

5. The discovery of a biological basis for homosexuality would be of great pastoral significance, allowing for a greater understanding of why certain persons struggle with these particular sexual temptations.

6. The biblical basis for establishing the dignity of all persons -- the fact that all humans are made in God's image -- reminds us that this means all persons, including those who may be marked by a predisposition toward homosexuality. For the sake of clarity, we must insist at all times that all persons -- whether identified as heterosexual, homosexual, lesbian, transsexual, transgendered, bisexual, or whatever -- are equally made in the image of God.

7. Thus, we will gladly contend for the right to life of all persons, born and unborn, whatever their sexual orientation. We must fight against the idea of aborting fetuses or human embryos identified as homosexual in orientation.
