Wendy VanderWal-Gritter’s book Generous Spaciousness (Brazos Press, 2014) is focused on making space for gay Christians within the church. The author has experience within ex-gay ministries, and the beginning focuses on how these have often been hurtful to those struggling with their religious and sexual identity.
What I’ve read of it makes it sound like it’d be a very helpful book, although she has become a bit of a controversial figure within the Christian Reformed Church.
