Next Session: Jan 06, 2025

The Vatican II Constitution on the Church Lumen Gentium proposes to “set forth” the “mystery” of the Church (LG 39; cf. 1-8). This way of speaking raises the question: in what sense is the Church a “mystery”? This course seeks to facilitate a deeper appreciation of the Church as a “mystery” from several points of view. Most basically, what is the “mystery” of the Church? How is this mystery reflected in the way Scripture speaks of the people of God? How is it related to the central mysteries of Christian faith? How is it nurtured and expressed by the Church’s worship? How might an understanding of the Church as mystery inform how we think about the Church as a community, about the Church’s mission, and about the Church’s ultimate destiny?
