Mysterium Fidei §17

¹⁷ St. John Chrysostom who, as you know, dealt with the Mystery of the Eucharist in such eloquent language and with such insight born of devotion, had these most fitting words to offer on one occasion when he was instructing his faithful about this mystery: "Let us submit to God in all things and not contradict Him, even if what He says seems to contradict our reason and intellect; let His word prevail over our reason and intellect. Let us act in this way with regard to the Eucharistic mysteries, and not limit our attention just to what can be perceived by the senses, but instead hold fast to His words. For His word cannot deceive." (5)
