Pope Francis is being laid to rest Saturday in a ceremony reflecting his priorities as pope and wishes as pastor: Presidents and princes will attend his funeral in St. Peter’s Square, but prisoners and migrants will usher him into the basilica where he will be buried. As many as 200,000 people are expected to attend the funeral, which Francis choreographed himself when he revised and simplified the Vatican’s rites and rituals last year. It was a reflection of Francis’ 12-year project to radically reform the papacy, to emphasize its pastors as servants, and to construct “a poor church for the poor.”
