A favorite mantra of the secular left is “follow the science.” It’s an appeal to empirical evidence and credentialed expertise over supernatural beliefs or partisan preferences. But increasingly on issues of gender and sexuality, the weight of evidence goes against the left’s narrative.

From the United Kingdom’s Cass Review last year to a recently published HHS report in the United States, the growing weight of evidence challenges the wisdom of “gender-transition” medical interventions for minors.

“The scientific support for gender-transition treatments in minors is exceedingly weak,” Joe Carter writes in his summary of the HHS report. “After reviewing the available research, HHS concluded that ‘the overall quality of evidence . . . is very low.’ The findings reveal little reliable proof that ‘gender-affirming care’ actually improves children’s long-term well-being.”

More reports like this will doubtless follow. These are helpful and clear resources for Christians as we speak up and advocate for policies that go with the grain of God’s creational design, not against it. True, good-faith science—insofar as it accurately observes the world God made—should be a natural ally for Christians. On transgenderism and so many other issues, we ought to appeal to both God’s Word (special revelation) and God’s world (general revelation). The book of Scripture and the book of nature always align, after all. Their Author is the same, and he doesn’t contradict himself.

Let’s honor the Author by drawing wisdom and mounting good arguments from both “books” as we counter the increasingly errant, reality-denying, antihuman philosophies and heresies of our day.
