Experts at UCLA estimate that 0.6% of American adults currently identify as transgender.

Like other writers covering religion, politics and culture, The Religion Guy has accumulated a bulging file on recent transgender conflicts, which go far beyond grade-school curriculums or women’s shelters, locker rooms and athletics. The major question facing practitioners, legislators and moral theologians is how the age-old “do no harm” principle applies to the greatly increasing numbers of teens under 18, especially girls, seeking transition via puberty blockers, hormone treatments and surgery.

A planned Memo analyzing those developments has been supplanted by a new book, “Gender Identity and Faith: Clinical Postures, Tools and Case Studies for Client-Centered Care” (InterVarsity Press) by Mark A. Yarhouse and Julia A. Sadusky, who are evangelicals and licensed clinical psychologists. Their work turns journalistic attention from the socio-political debates to the situations of transgender individuals, especially those raised in traditional forms of religious faith.

A blurb from Laura Edwards-Leeper, who chairs the child and adolescent committee of the World Professional Association for Transgender Health, considers this book “essential” for mental health providers. But The Guy thinks it’s equally pertinent for individual clients, parents, pastors and churches (and journalists!) seeking understanding.

Even The Christian Century thinks that though the book “will at times disappoint” fellow religious progressives, it may “prove an important harm-reduction tool and entry point for conservatives who are struggling to join the conversation.”

The bottom line: Considering the timeliness and difficulty of the topic, The Guy sees it as a Book of the Year prospect in religion, and a compelling topic for journalism.
