Father Shay is an excellent Spiritual Theologian. (Spiritual Theology is the intersection of people's lived experience with Scripture/Theology - how theology actually affects people, and whether certain theologies lead to spiritual growth or stagnation.) This is a must read for everyone involved with spiritual theology - spiritual directors, pastors, lay leaders, chaplains, anyone in a pastoral care type role. Beautifully and clearly written, In the Margins weaves Fr. Shay's own story through the contours of both Old and New Testaments, and carefully, meaningfully, examines the theology he had been given. This book is not just for those who are transgender: people who are deconstructing their faith, who grew up in female bodies, and/or who grew up closeted in evangelical spaces will feel seen, known, and validated. As someone who fits all three of those categories, I can confirm that the theologies Fr. Shay analyzes are widespread and his conclusions about them are accurate. I'm sure transgender and genderqueer individuals who grew up in evangelical spaces will also feel seen, known, and validated by this work. (Also, people who have been divorced). I strongly encourage people who do not fit any of those categories to read this as well. Please listen to us, and believe us when we tell you that many theologies made by and for straight cis men are causing deep harm to over half of the church (cis women, gay, and genderqueer people).
Fr. Shay also does a very good job with Biblical Theology. (Biblical Theology is analyzing/exegeting the text of Scripture in context). I am a seminarian at Talbot School of Theology, studying to be a Biblical Theologian. I do not agree with all of Fr. Shay's interpretations. But it is important to remember that he is, first and foremost in this work, doing spiritual theology. One may be tempted to compare his work to other, more exegetical works, but please try not to. It is important to analyze any literature according to its relevant genre, and Spiritual Theology has looser rules than Biblical Theology. It is about seeing yourself in Scripture and about connecting with God and growing in the fruit of the Spirit. Biblical Theology is about trying to figure out the most likely interpretation of a given text. It is more stuffy and academic, and doesn't always have meaningful application. All that to say, when you get to the part about Joseph perhaps being trans, don't stop reading!! I think the link between his coat and the garments worn by the princesses in 2 Sam 13 is a bit of a stretch, but it is the kind of stretch allowable in this genre of writing. It doesn't mean that he isn't good at exegeting, it means that he's using a different framework than someone like me would use, and that's ok.
Again, In the Margins is truly excellent. I plan to have several in my library to hand out to people freely. It meets a huge need for trans voices in the church. In an environment where seemingly everyone has something to say about trans people, the best way to love our neighbors is to turn off the fear mongering and listen to actual stories from our queer siblings in Christ.
