Vatican II at 60: A timeline of key moments

CNA, AC Wimmer: Oct. 11 marks the 60th anniversary of a monumental event in the history of the Catholic Church: the gathering in Rome of bishops from around the world for the start of the Second Vatican Council.

Vatican II, as it is popularly known today, was not one long, singular meeting, but rather a complex series of four deliberative sessions held between 1962 and 1965.

Nor was the council held for one, specific purpose, but rather many reasons, though aggiornamento — the desire to connect the Church with the modern world — served as a rallying theme.

What happened at those four sessions in St. Peter’s Basilica and resulted in four constitutions as well as many other texts has shaped and will continue to shape — and reverberate throughout — the Catholic Church for many years. Report is here.
