Book excerpt: The Catholic Commentary on Sacred Scripture series has proven widely successful, with series volumes having sold over 250,000 copies. Designed to complement the CCSS, this new series on the seven Sacraments provides readers with a deeper appreciation of God's gifts and call in the Sacraments through a renewed encounter with God's Word. Leading Catholic teacher and popular speaker John Bergsma offers a biblical theology of marriage rooted in the Old and New Testaments that will be interesting and informative to the church catholic. This book shows the biblical basis for the teaching that marriage is a sacrament. It provides lay teachers with background and depth on topics taught frequently in the parish, making it suitable for classroom use and parish ministry. The series editors are Timothy C. Gray and John Sehorn. Gray is president of the Augustine Institute, which has one million subscribers to its online content channel, Formed.org. Gray and Sehorn both teach at the Augustine Institute Graduate School of Theology, which prepares students for Christian mission through on-campus and distance education programs.
