From the Holy and August Sacrifice of the Mass, this is said after the Consecration of the Eucharist in the prayers before Holy Communion (with Holy Communion being, of course, obligatory by the priest, and non-obligatory to everyone else):
Let not the partaking of Thy Body, O Lord, Jesus Christ, which I, though unworthy, presume to receive, turn to my judgment and condemnation; but let it, through Thy mercy, become a safeguard and remedy, both for soul and body; Who with God the Father, in the unity of the Holy Ghost, livest and reignest God, world without end. Amen.
Percéptio Córporis tui, Dómine Iesu Christe, quod ego indígnus súmere præsúmo, non mihi provéniat in iudícium et condemnatiónem: sed pro tua pietáte prosit mihi ad tutaméntum mentis et córporis, et ad medélam percipiéndam: Qui vivis et regnas cum Deo Patre in unitáte Spíritus Sancti Deus, per ómnia saecula sæculórum. Amen.
Yet again, we owe Trad Inc a massive debt of gratitude for showing us how the One, Holy, Catholic and Apostolic Church has been wrong for its entire 2000 year history. Imagine that – every Mass containing error!
Finally, at long last, this two millennia of pious virtue signaling and “superstitious magical thinking” with regards to the Eucharist*** is called out for what it is!
***Honorable mention to Pharisaic/Rabbinic/Talmudic Judaism for exactly the same rhetoric.
First the Papacy, now the Eucharist! Thank you, Trad Inc! Thank you Freemasonry! Thank you Talmudic Judaism! Thank you for setting us straight!
Now, let us all return to our tee-vee shows, video games, and stage-4 social media addictions like REAL Catholics!
