As Pope Emeritus Benedict lies in state at St. Peter's Basilica in Vatican City awaiting burial, many are reflecting on his eight-year legacy as the head of the Catholic Church. Among them is David Gibson, author of the book "The Rule of Benedict: Pope Benedict XVI and His Battle with the Modern World." In an interview with Africa 54 managing editor Vincent Makori, Gibson described Benedict's relationship with Africa, which included visits to Benin, Angola and Cameroon.
