Father Barron explores the ancient practices of the Church’s worship that endure to this very day, and the notion that “all value is summed up in the liturgy, the supreme act by which we commune with God.” Considered by the Catholic Faith to be “the source and summit” of its identity and mission, the Eucharist is the central practice of the Church’s culture. Father Barron describes all the parts of the Mass, and shows how the Sacred Liturgy embodies the whole of the Faith in diverse places as Jerusalem, Rome, Chicago, Orvieto, Mexico City.
