The Reciprocity Between Faith and Sacraments in the Sacramental Economy

The Sacraments are at the very centre of the Christian life, yet many today receive them without a clear understanding of what the graces they signify and contain. This document from the International Theological Commission explores the relationship between the faith of the recipient and the power and grace conferred by the sacrament looking at what is needed for the fruitful reception of the sacraments in order for them to help the receiver grow in faith.
There is “a profound unity between the act by which we believe and the contents to which we give our assent…. In the Christian conception it is not possible to think of a faith without sacramental expression, nor a sacramental practice in the absence of ecclesial faith” [51] The document treats each sacrament but gives saves its most comprehensive treatment for marriage exploring the challenges posed by the increasing number of marriages where the spouses have an incomplete understanding of marriage as a sacrament.
