I hadn’t seen Adam Hamilton’s book Seeing Gray in a World of Black and White. From this review, it sounds like it might be worth a read:
Hamilton does not assume the reader has a great deal of biblical training, but he does assume the reader is thoughtful. … Generally each chapter summarizes two extreme positions and seeks the common ground between the two.
Church people probably don’t do enough of that. Years ago, I was impressed by “The Truth Between Us,” a sermon series by Erwin McManus at Mosaic where he took the same approach in discussing various world religions from a Christian perspective.
