I have an article up at Christianity Today titled, “Understanding the Transgender Phenomenon,” where I introduce three contrasting lenses through which people see and respond to gender dysphoria and related matters. I also discuss the importance of not equating gender congruence with spiritual maturity:
We can be sensitive, though, not to treat as synonymous management of gender dysphoria and faithfulness. Some may live a gender identity that reflects their biological sex, depending on their discomfort. Others may benefit from space to find ways to identify with aspects of the opposite sex, as a way to manage extreme discomfort. And of course, no matter the level of discomfort someone with gender dysphoria experiences (or the degree to which someone identifies with the opposite sex), the church will always encourage a personal relationship with Christ and faithfulness to grow in Christlikeness.
Those interested in the topics of gender dysphoria and the experiences of transgender persons, including Christian transgender persons, might be interested in the book, Understanding Gender Dysphoria.
