Three Hours' Agony

The Three Hours' Agony is a Christian service held in Roman Catholic, Lutheran, Anglican and Methodist churches on Good Friday from noon till 3p.m. to commemorate the three hours of Christ's hanging at the cross.
The Jesuit priest Alphonsus Messia is said to have devised this devotion in Lima, Peru. It was introduced to Rome around 1788 and spread around the world to many Christian denominations. In 1815, Pope Pius VII decreed a plenary indulgence to those who practise this devotion on Good Friday.
