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.
Papal primacy
At the Second Vatican Council (1962–1965) the debate on papal primacy and authority re-emerged, and in the dogmatic constitution "Lumen gentium", the Catholic Church's teaching on the authority of the pope, bishops and councils was further elaborated. Vatican II sought to correct the unbalanced ecclesiology left behind by Vatican I. The result is the body of teaching about the papacy and episcopacy contained in "Lumen gentium".
