“What was visible in our Savior has passed over into his mysteries.” (Saint Leo the Great)

226. What is the link between the sacraments and the Church?
1117-1119
Christ has entrusted the sacraments to his Church. They are the sacraments “of the Church” in a twofold sense: they are “from her” insofar as they are actions of the Church which is the sacrament of Christ’s action; and they are “for her” in as much as they build up the Church.
