Vatican II

What Was Vatican II?

The Second Vatican Council, commonly called Vatican II, was the twenty-first Ecumenical Council of the Catholic Church.

It was convened by Pope St. John XXIII in 1962 and continued under Pope St. Paul VI until its conclusion in 1965.

The council gathered more than 2,500 bishops from around the world to discuss the life, mission, and renewal of the Church.

Vatican II did not create a new religion, abolish Catholic doctrine, or replace previous Church teaching.

Rather, it sought to present the unchanging Catholic faith more effectively to the modern world.
