Sexuality and the Christian Body: Their Way into the Triune God by Eugene F. Rogers, Jr., is a phenomenal work that navigates the Epistles to the Romans, Thomas Aquinas, and Karl Barth in ways that remain faithful to the text and at the same time pushes them to consider *orthodox ways to accept same-sex marriage. This has been really helpful for me as I consider myself theologically conservative in my approach to the Tradition, Scripture, and other things related to the Christian faith. It is expensive, but sometimes there are cheaper editions on thriftbooks or whatnot. EDIT: I mention my theologically conservative inclinations because, to be quite honest, there are very few LGBT+ affirming works that are appealing to a theologically conservative Christian. The late Richard Hays’ book, for example, requires rejection of Divine Simplicity (and more specifically, God’s immutability) in order to accept same sex marriage. This book does not require denial of the creeds nor of classic doctrine in order to be affirming.
