Pope John XXIII called the Council because he felt the Church needed "updating". In order to connect with 20th century people in an increasingly secularized world, some of the Church's practices needed to be improved, and its teaching needed to be presented in a way that would appear relevant and understandable to them.

Roman Catholic bishops at the Second Vatican Council (1962-1965) called for outlawing war by international consent and creating a universal public authority that would safeguard security, justice, and human rights. In their encyclicals, Pope John XXIII, Pope Benedict XVI, and Pope Francis have stated that there is an urgent need for a true world political authority that would be regulated by law, observe the principles of subsidiarity and solidarity, promote human development, manage globalization, and establish the common good.
