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.

Reginald ("Rex") King, who had been elected secretary of the short-lived New Mexico "National Assembly", dissolved by Remey in 1964. Unhappy about Remey's resistance to his leadership role in the United States, King eventually went to Italy where Remey was living, and had an apparently acrimonious meeting with him. Following this encounter, on 13 September 1969 Remey issued a letter denouncing King: "his station to be ever and eternally that of Satan for evermore". King switched his allegiance to Marangella when the latter advanced his own claims two months later.

This relationship, however, also soon broke down. King decided that Marangella had made "a number of faulty 'interpretations' of the Writings" and declared that Marangella "had ceased to fulfill the requirements of the office of guardian". He argued, indeed, that "neither Mason Remey nor Joel Marangella had in truth ever been guardians … because of the lack of lineal descendancy" (i.e., from Bahá'u'lláh). What Remey had actually been, King said, was "a regent", and King came to the "realization" that he himself "was in actuality the Second Regent…." [Mason Remey and Those Who Followed Him]
