In this exciting new book Thomas Nash refutes the common charge that the Mass is “unbiblical” in a resoundingly biblical fashion. From the Garden of Eden to Christ's Ascension, the biblical roots of the Mass go much deeper than the Last Supper and Christ's Passion. Old Testament sacrifices like Abel’s, Abraham’s and the Passover all prefigure and are fulfilled by Christ's Sacrifice, which is made present in the Sacrifice of the Mass. What began on the Cross culminated in everlasting glory when Jesus entered “once for all” into the heavenly holy of holies, as the Letter to the Hebrews provides. In a time when the Catholic Church is under attack from within and without, Worthy is the Lamb reminds the faithful that the Mass is, as Vatican II affirms, “the source and summit of the whole Christian life.” This book will transform your understanding of and participation in the Mass. “It’s high time Catholics discovered the Old Testament roots of our Church’s worship and priesthood. The New Covenant did not abolish the Old, but fulfilled and transformed it. Our Lord wants us to experience the reality of the Mass in all its fullness, and that’s what Tom Nash wants you to know.” —Scott Hahn, Ph.D. Thomas Nash is a Senior Information Specialist for Catholics United for the Faith.
