“The social gospel has poisoned the church twice”

From Reformation 21:

Dr. Keller made the following provocative comment: ‘The social gospel has poisoned the church twice.’  The first time, of course, was when the social gospel was first introduced as a (theologically) liberal agenda that minimized the preaching of the gospel.  But the social gospel is poisoning us again, Keller argued, because today evangelicals are so concerned about falling into the error of the old social gospel that we do not put nearly the emphasis that the Bible places on caring for the poor.
