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.
Catholic Church and ecumenism
"The search for Christian Unity was one of the principal concerns of the Second Vatican Council."
This was attested to even from the moment the Council was announced, by Pope John XIII, during the vespers closing the Octave of Prayer for Christian Unity, on 25 January 1959, at the Basilica of Saint Paul's Outside the Walls.
