seminarians at the same time dropped by three quarters. More pronounced declines were evident in religious life where the number of sisters and brothers declined sharply. Infant baptisms began to decline almost at once after Paul's election and did not begin to recover until 1980. In the same period adult conversions to the church declined by a third. While marriages increased annulments also increased but at a much greater rate. There was a 1,322% increase in declarations of nullity between 1968 and 1970 alone. While 65% of US Catholics went to Sunday Mass in 1965, that percentage had slipped to 40% by the time of Paul's death. Similar collapses occurred in other developed countries. Paul VI did renounce many traditional symbols of the papacy and the Catholic Church; some of his changes to the papal dress were reversed by Pope Benedict XVI in the early 21st century. Refusing a Vatican army of colourful military uniforms from past centuries, he got rid of them. He became the first pope to visit five continents. Paul VI systematically continued and completed the efforts of his predecessors, to turn the Euro-centric church into a church of the world, by integrating the bishops from all continents in its government and in the Synods which he convened. His 6 August 1967 motu proprio Pro Comperto Sane opened the Roman Curia to the bishops of the world. Until then, only Cardinals could be leading members of the Curia. Some critiqued Paul VI's decision; the newly created Synod of Bishops had an advisory role only and could not make decisions on their own, although the Council decided exactly that. During the pontificate of Paul VI, five such synods took place, and he is on record of implementing all their decisions. Related questions were raised about the new National Bishop Conferences, which became mandatory after Vatican II. Others questioned his Ostpolitik and contacts with Communism and the deals he engaged in for the faithful. The pope clearly suffered from the responses within the church to Humanae vitae. Most regions and bishops supported the pontiff, including notable support from Patrick O'Boyle. However, a small part of the church, especially in the Netherlands, Canada, and Germany openly disagreed with the pope, which deeply wounded him for the rest of his life.
