Book excerpt: The sacramental economy was instituted by Christ and entrusted to His Church in order to build up the Body of Christ in a twofold communion: binding the members together with God and one another. Touched by Christ: The Sacramental Economy is an introductory course on Sacramental Theology suitable for all who seek a deeper understanding of how the Church’s sacraments constitute channels of grace, nurture supernatural life, and heal us from our sins. Lawrence Feingold expertly describes the nature of the sacraments; their purpose, fittingness, and relationship with Christ and the New Covenant; their relationship with the Old Covenant rites that prefigured them; the character and grace that they communicate; and the nature of their causality. Touched by Christ shows that the sacraments of the New Covenant should be understood as instruments of Christ’s humanity that are used as words of power to communicate the sanctification that they signify, infuse grace, communicate the Holy Spirit, and build up ecclesial communion in those who receive them with the right dispositions.
