⁣Pope John Paul II organized the first World Day of Prayer for Peace in Assisi, Italy, on October 27, 1986 at the basilica of St. Francis. In all there were 160 religious leaders who spent the day together with fasting and praying to their god or gods.
Each religion was lent a chapel in the ancient church, in order that they would be able to worship in the way they chose.
At this meeting, under the pope’s presidency, assortment of Hindus, Tibetan lamas, Japanese bonzes, tribal snake worshippers, and animists of all sorts performed their respective rites, some of the less mainstream officiants showing a little embarrassment at having to exhibit their customs outside the privacy of their native groves and temples. For a day, the town of St. Francis was given over to displays of pagan worship. Cardinal Silvio Oddi reported that a group of Buddhists entered the church of San Pietro, set up a statue of Buddha on the tabernacle of the altar and venerated it with prayer scrolls and incense. 12 years after this event, after no bishop or cardinal attempted to re-consecrate the basilica or make any public reparation, the city was struck with a series of earthquakes, taking the lives of 11 and causing the Upper Church to collapse.

“You shall fall among the ruins of your idols, and my soul shall abhor you.”
