With one exception...

If a biological basis is found, and if a prenatal test is then developed, and if a successful treatment to reverse the sexual orientation to heterosexual is ever developed, we would support its use as we should unapologetically support the use of any appropriate means to avoid sexual temptation and the inevitable effects of sin.
--Albert Mohler, here.

Mohler is the president of the Southern Baptist Theological Seminary. By "a biological basis" he means "a genetic or hormonal cause for sexual orientation." By "we" he means "Christians who are committed to think in genuinely Christian terms." So now that the terms are defined, his point bears repeating: if expecting parents could know that their child would be born gay, and if medicine developed a prenatal treatment, Christians should stand behind this treatment.

You have to wonder what Mohler would feel about prenatal treatments for autism, slow metabolism, or short torsos. But something tells me you already do.
