Rich descriptions of the theology behind the elements of the Mass are enfleshed by concrete stories of how real people contribute to what Jesus Christ, through the power of the Holy Spirit, wants his great gift of the Eucharist to achieve: shaping families and peoples, tribes and nations, cities, and the cosmos according to the great dream that He shared the night before He died when he prayed to the Father: "that they may all be one" (Jn 17:21).
