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.
Unitatis redintegratio
Unitatis redintegratio (Latin for "Restoration of unity") is the Second Vatican Council's decree on ecumenism. It was passed by a vote of 2,137 to 11 of the bishops assembled, and was promulgated by Pope Paul VI on 21 November 1964. Its title is taken from the opening words of the Latin text. The opening of the document's English translation is: "The restoration of unity among all Christians is one of the principal concerns of the Second Vatican Council."
