Input: Read this: 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 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.
