Samuel Ruiz
In 1962, the Second Vatican Council (1962-1965) convened, focusing on the social responsibility of Christians and on opening the Church to theological development and dialogue. Vatican II encouraged that sermons be translated and read to communities in their local languages and that the Church be more involved in addressing social problems, such as those occurring in Central and South America. For Ruiz, his participation in the Second Vatican Council allowed time for reflection on the decisions and actions carried out under his administration, which brought him a long way from the somewhat naïve enthusiasm which he’d had during his first years as bishop. It was Vatican II which inspired Ruiz to translate scripture into local indigenous languages and into practice, with an emphasis on inculturation.
Nostra aetate
Nostra aetate () is the Declaration on the Relation of the Church with Non-Christian Religions of the Second Vatican Council. Passed by a vote of 2,221 to 88 of the assembled bishops, this declaration was promulgated on 28 October 1965 by Pope Paul VI. It is the shortest of the 16 final documents of the Council and "the first in Catholic history to focus on the relationship that Catholics have with Jews." It "reveres the work of God in all the major faith traditions." It begins by stating its purpose of reflecting on what humankind have in common in these times when people are being drawn closer together.
