The church in the US has many things to say to culture about how to minister to the poor, how to advocate for the weak and how to value family. But one area of social justice that seems to consistently be missing (or at least under-addressed) is the role of minorities among predominately White denominations and parachurch organizations.
There was a point in the late 90s (at least in my Evangelical circles) where issues of racial reconciliation were fairly common. There were books written, Promise Keepers made it one of their central tenets, and many denominations formed study groups. But over the past decade it seems to me that not much has really changed.
I have heard multiple good reviews about Aliens in the Promised Land: Why Minority Leadership is Overlooked in White Christian Churches and Institutions by Anthony Bradley. Brian LePort at NearEmmaus has a thorough review of the content and some good push backs (primarily around the fact that there are no women represented in the book). Dr Bradley commented on the post and said he felt that there was too much to talk about when including both gender and race. So he has a second book that he is working on that focuses particularly on minority women in the Church.
I would encourage you to at least read the review and then pick up a copy of the book.
