John Colwell presents a robust sacramental theology for Protestant churches. He maintains that a doctrine of the Trinity leads us to conceive of God's gracious engagement with his creation as one that is mediated through that creation. This theory lies at the foundation for an understanding of the sacraments. Colwell further argues that the Church and Scripture confer context, definition, and validity on all other sacramental events.The final section reconsiders the seven Sacraments of the Catholic tradition in the light of the understanding of sacramentality developed earlier in the book: baptism, confirmation, the Lord's Supper, cleansing, healing, ministry, and marriage.Colwell discusses the Sacraments from an evangelical perspective but with a committed ecumenical intent.
