Quite possibly one of the best books on the sacraments I have ever read. The connection of the Seven Sacraments with the Covenants of the Old Testament and the New and Eternal Covenant is presented in a cogent and wonderful way. All Catholics and all protestants can learn a lot from the exegesis given by Scott Hahn.
The chapters focusing on marriage are as good an explanation of the Catholic doctrine of Sacramental Matrimony. I reflect that all can hope and pray that Scott Hahn's understanding, which gained a full imprimatur from Holy Mother Church, is held up by the Synod on the Family later this year. Marriage is not a burden that we can dissolve, the sacramental nature of marriage will indeed offer the ability for couples to overcome any struggle.
I highly recommend this book. It will enhance your understanding of the One Holy Catholic and Apostolic Church.
