1982. At the centre of the bank's failure was its chairman, Roberto Calvi, and his membership in the illegal Masonic Lodge Propaganda Due (aka P2). The Vatican Bank was Banco Ambrosiano's main shareholder, and the death of John Paul I in 1978 is rumoured to be linked to the Ambrosiano scandal. Calvi, often referred to as "God's Banker", was also involved with the Vatican Bank, Istituto per le Opere di Religione, and was close to Bishop Paul Marcinkus, the bank's chairman. Ambrosiano also provided funds for political parties in Italy, and for both the Somoza dictatorship in Nicaragua and its Sandinista opposition. It has been widely alleged that the Vatican Bank provided money for Solidarity in Poland. Calvi used his complex network of overseas banks and companies to move money out of Italy, to inflate share prices, and to arrange massive unsecured loans. In 1978, the Bank of Italy produced a report on Ambrosiano that predicted future disaster. On 5 June 1982, two weeks before the collapse of Banco Ambrosiano, Calvi had written a letter of warning to John Paul II, stating that such a forthcoming event would "provoke a catastrophe of unimaginable proportions in which the Church will suffer the gravest damage". On 18 June 1982 Calvi's body was found hanging from scaffolding beneath Blackfriars Bridge in the financial district of London. Calvi's clothing was stuffed with bricks, and contained cash valued at US$14,000, in three different currencies.

These issues included demanding a return to the Tridentine Mass, as well as the repudiation of reforms instituted after the Second Vatican Council, such as the use of the vernacular language in the formerly Latin Roman Rite Mass, ecumenism, and the principle of religious liberty. In 1988, the controversial traditionalist Archbishop Marcel Lefebvre, founder of the Society of St. Pius X (1970), was excommunicated under John Paul II because of the unapproved ordination of four bishops, which Cardinal Ratzinger called a "schismatic act". The World Day of Prayer for Peace, with a meeting in Assisi, Italy, in 1986, in which the pope prayed only with the Christians, was criticised for giving the impression that syncretism and indifferentism were openly embraced by the Papal Magisterium. When a second Day of Prayer for Peace in the World was held in 2002, it was
