I've heard the quote once too often. It's time to set the record straight—about the quote, and about the gospel.
Francis of Assisi is said to have said, "Preach the gospel at all times; when necessary, use words."
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 . . .
Go read the whole thing.
It is true that too many churchfolk are all talk, no action.
It is also true that the Bible never ceases to command us to speak boldly, to preach the gospel, by which it means with our mouths.
It's a two-fisted gospel, folks.
