Lex Orandi, Lex Credendi is a traditional Catholic principle maintaining that the law of prayer is the law of belief. In other words, the way we pray—especially at Mass—expresses and shapes our faith in Jesus Christ and our relationship with Him as His disciples.
What is the divine architecture of the Mass, in which we are invited to participate? What grace does Our Lord offer to us when we pray and prepare to receive Him in Holy Communion? With what blessing, understanding and mission do we go forth, when the Mass is ended?
