I've purchased this book, but have not had the chance to read it yet. I came across this review from Christianity Today. http://www.christianitytoday.com/ct/2011/july/quicktakes-jul11.html
by Tony Merida and Rick Morton (New Hope Publishers)
Christians do not approach orphan care as mere humanitarians but as people adopted by God through the work of Jesus Christ. Orphanology provides the burgeoning orphan care movement with a gospel-centered theological foundation as well as a comprehensive plan for getting involved at many levels, including adoption, orphanage restoration, foster care, and transitional assistance. Between adoption stories, Tony Merida and Rick Morton offer a compelling picture of how the gospel motivates us to action on behalf of the fatherless.
