Pope Francis on Friday evening was leading a service at St. Peter's Basilica in the Vatican to mark Good Friday, the most solemn day in the Christian calendar. Later Friday, he will take part in a nighttime ceremony marking the Stations of the Cross, also known as the Way of the Cross or Via Crucis, at Rome's Colosseum -- one of the city's best known landmarks. Roman Catholics worldwide will reflect Friday on the gospel account of the Lord's Passion, recalling the day Jesus died on the cross before rising three days later, according to Christian doctrine. Holy Week, one of the most significant periods of the Roman Catholic year, will culminate on Easter Sunday with a Mass in St. Peter's Square, led by the pope.
