This course was formerly THEO 342. The Second Vatican Council (1962-1965) was the major event in the Church in the twentieth century. It is also perhaps the most misunderstood event. There were four Constitutions, which are the highest ranking documents issued by a Council: two on the Church, one on divine Revelation, and one on the Sacred Liturgy. This course will focus the Second Vatican Council’s documents on the topics of the Church (ecclesiology) and Her liturgy. Specifically, this course will deal with two documents that deal with the Church Lumen Gentium and Gaudium et Spes and one that deals with liturgy, Sacrosanctum Concilium.
