Fr. Z's Store > Lex Orandi Lex Credendi
The Catechism of the Catholic Church states: "The Church's faith precedes the faith of the believer who is invited to adhere to it. When the Church celebrates the sacraments, she confesses the faith received from the apostles - whence the ancient saying: lex orandi, lex credendi (or: legem credendi lex statuat supplicandi, according to Prosper of Aquitaine). The law of prayer is the law of faith: the Church believes as she prays. Liturgy is a constitutive element of the holy and living Tradition."
