"It is the Holy Sacrifice of the Mass that teaches us our theology, not the other way around."
I found this profound."It is the Holy Sacrifice of the Mass that teaches us our theology, not the other way around."
The Mass is not simply an ecclesiastical law, a matter of discipline for the Latin (Western) Church, as even laymen are familiar with the principle enunciated by Pope St. Celestine I to the bishops of Gaul (422): “Legem credendi, lex statuit supplicandi” [the law of praying has established the law of believing], often shortened to “Lex orandi, lex credendi” [the law of praying (is) the law of believing]. In other words, it is the Holy Sacrifice of the Mass that teaches us our theology, not the other way around. The Mass comprises the Apostolic Tradition of faith and morals in its very essence. Every doctrine essential to the faith is taught in the text of the Mass. The notion that one pope can “overrule” his predecessors in such a matter is in implicit denial of the credal dogma that the Church is Apostolic.
