Vatican II: Welcome

A Gumberg Library Research Guide

Just three months after his election as pope, John XXIII announced his intention to call an ecumenical council for the renewing or "updating" of the Church.

This, the Second Vatican Council, was held in four sessions during the years 1962 through 1965. According to the Dictionary of the Ecumenical Movement, the issues discussed and debated by the Council included "divine revelation, the church, the liturgy, bishops' pastoral office, the ministry and life of priests, priestly formation, the laity, Christian education, religious life, Eastern Catholic churches, the church in the modern world, missionary activity, ecumenism, non-christian religions, religious freedom, and the communciations media" (p. 1189).

 In 1963, Pope John died, so according to canon law, the Council was suspended. But Paul VI, John's successor, announced that the Council should continue.

The results of the Vatican II deliberations were 16 documents, the ideas from which have effected every aspect of faith and practice in the Roman Catholic Church. Again, according to the Dictionary of the Ecumenical Movement, "Without taking account of the debates and resolutions of Vatican II, it is impossible to understand the modern Roman Catholic Church" (p. 1189).

This research guide will connect the researcher to many types of resources available through the Gumberg Library and on the web pertaining to this important council that reshaped the Roman Catholic Church for the modern world.
