(London Telegraph) It has been dubbed “the day of the four popes”, an unprecedented occasion that has never before taken place in the 2,000-year-history of the Catholic Church.

It promises to be the biggest Vatican event since millions of pilgrims descended on St Peter’s Basilica for the funeral of John Paul II in 2005.

On Sunday morning, under the gaze of a billion Catholic faithful around the world, the Polish pontiff will be made a modern-day saint along with one of his predecessors, Pope John XXIII, nicknamed the “Good Pope”, who presided over crucial reforms to the Catholic Church during the 1960s.
