Christian Mystery›SECTION ONE THE SACRAMENTAL ECONOMY›CHAPTER ONE THE PASCHAL MYSTERY IN THE AGE OF THE CHURCH›III. The Sacraments of Faith
"The purpose of the sacraments is to sanctify men, to build up the Body of Christ and, finally, to give worship to God. Because they are signs they also instruct. They not only presuppose faith, but by words and objects they also nourish, strengthen, and express it. That is why they are called 'sacraments of faith."'
