The Sacramental Mystery
This book, now in its third edition, outlines how the sacraments are the chief means in the Church through which God's people are reconciled to the Father, through his Son, by the power of the Holy Spirit. It illustrates classical issues like the conditions for the validity and efficacy of the sacraments, as well as the minister, recipient and effects of these sacred mysteries; it deals with particular topics like the necessity of Baptism, the sacrificial nature of the Eucharist, and the nature of Marriage. The work also explores how new ecumenical questions affect Christian sacramental understanding.
