In light of the recent discussions, old and new readers of this blog maybe interested in this new book by Kevin D. Young and Ted Kluck titled Why We Love the Church: In Praise of Institutions and Organized Religion (Moody, 2009). A study guide for the book is located online here (free).
Check out their quick YouTube introduction. I know their focus is not on the heresy of Camping (i.e. get out of the Church), but this book is quite relevant.
Tim Challies review’s the book here.
Many of us could recommend excellent treatments on the doctrine of the church; Thomas E. Peck’s Notes on Ecclesiology is one I would recommend. Purchase it here
