“Preach the gospel at all times; when necessary, use words.”  How many (hundreds of!) times have you heard that line rolled out?  The good part about the alleged saying is that we do need to communicate that we truly believe the gospel through what we do.  People need to see the gospel as well as hear it.  If you have any doubts about this, please refer to my post from a few days ago on “justice and mercy” ministries.  But there are two problems with the way this quote is normally used.  First, it is often used by people who are oriented toward social concern but who are less comfortable with verbally proclaiming the good news about the death and resurrection of Jesus Christ and faith in him alone.  Such hesitancy to share the gospel verbally simply will not do if you even remotely consider yourself to be a biblical Christian.  Second, Francis of Assisi apparently never said it.

Mark Galli, the senior managing editor of Christianity Today and who wrote a biography of Francis, made the following comment: 

"This saying is carted out whenever someone wants to suggest that Christians talk about the gospel too much, and live the gospel too little.  Fair enough—that can be a problem.  Much of the rhetorical power of the quotation comes from the assumption that Francis not only said it but lived it.

The problem is that he did not say it.  Nor did he live it.  And those two contra-facts tell us something about the spirit of our age."
