Let’s take the Mass, for instance. Scott Hahn, a world-renowned Catholic theologian converted from evangelical Calvinism, surreptitiously attended a Catholic Mass in Wisconsin in the early 1980s before his conversion. Bible in hand, he began to follow this “strange” liturgy in an attempt to take notes and return to his students to show how the Catholic Mass was the ultimate sacrilege.
Long story short, Hahn states that “something hit me.” He realized that the words on the liturgy of the Mass were coming from the open Bible beside him. A line from Isaiah, another from Paul, another from a psalm.
Hahn learned later that during the Liturgy of the Word, Catholics, over a three-year period, hear the Scriptures proclaimed from the Old and New Testaments and the four Gospels. Furthermore, Hahn points out, during the Eucharistic Liturgy part of the Mass, the believer is drawn not only into the Last Supper but also into the glorious New Heavenly Jerusalem of the Book of Revelation with all its hymns and praises.
