CT senior managing editor Mark Galli--author of a biographical guide to Francis of Assisi--has a good article online today on the quote "Preach the gospel; use words if necessary."
"The problem," Galli writes, "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."
Mark closes by proposing a more biblical injunction: "Preach the gospel—use actions when necessary; use words always."
