What are sacraments? This article shows that sacraments are visible signs and seals of God’s invisible grace promised to his people in the gospel. Both baptism and Lord's Supper point us to the work of Christ.
This article explains the ways in which the sacraments are efficacious by virtue of participation in them. The Lord's Supper is a means by which the church manifests itself as one body, and baptism effects membership in the church and displays the shape of the church and its position over against the world.
