Pope Francis made a busy two-day visit to the city of Turin in northern Italy this week (June 21-22). He prayed before the famed Shroud of Turin, held by some to be Christ’s burial cloth. He also celebrated a Mass before a gathering of an estimated 100,000 people. On the final day of his trip, he became the first pope to visit a Waldensian church, an evangelical group that was excommunicated by the Catholic Church in the 12th century. He apologized for the Catholic Church’s past persecution of the Waldensians.
