What was the modern council that renewed the church?

The modern council that played a significant role in renewing the Catholic Church is the Second Vatican Council, which took place from 1962 to 1965. It aimed to address relations between the Catholic Church and the modern world, promoting reforms in liturgy, ecumenism, and the Church's approach to social issues. Vatican II produced several key documents that encouraged greater engagement with contemporary society and fostered a spirit of openness and dialogue within the Church.
