In Swear to God, Dr. Scott Hahn explores the richness of Christ's sacraments, their doctrine, history, symbols, and rituals. Drawing upon the Bible and the Church's tradition, he shows how God's covenants with Adam, Noah, Abraham, Moses, and David became the driving forces in history. When Jesus came to fulfill all these covenants, He established a new covenant, with greater power than ever before. Christians are God's children now. Joined to Christ by baptism, we can already share in the eternal life of the Trinity, a life we hope to know fully in heaven. But heaven is with us, even now, in the sacraments.
