A new guide to Catholic social teaching, DoCat, has been launched at World Youth Day by Cardinal Luis Tagle. Like its predecessor, the youth catechism YouCat, it uses a bite-size question-and-answer format, and is heavily illustrated with photos, cartoons, and quotations. Pope Francis has contributed a preface.

The quotations draw heavily on Scripture and the saints, but also include such figures as Bruce Willis, quoted in the section on new media for his observation that: “The internet is a place for searching, copying and browsing. At worst it is a place for executions. sexual abuse, a place for data mining and privacy groups. More trivially, it is a world of escapist nonsense.”
