Definition
The Vatican Councils refer to two major ecumenical councils of the Catholic Church held in Vatican City, Rome 🇮🇹. Vatican I (1869-1870) defined papal infallibility. Vatican II (1962-1965) modernized the Church's approach to the world. Think of them as major updates to the Catholic Church's operating system ⛪. They addressed issues ranging from doctrine to social justice. These councils have significantly shaped the modern Catholic Church.
