I already know the answer to this question is “no. you can’t. so don’t.”
But I LOVE the Eucharist, and the Eucharist is described as the “source and summit” of our Catholic faith. So why is it not in one of the most central prayers, The Apostle’s Creed?
If the institution of the Eucharist (and the sacraments of baptism and confession) was done for our salvation, then why would the text not be “… was born of the Virgin Mary, and became man. For our sake he INSTITUTED THE SACRAMENTS, suffered under Pontius Pilate, was crucified, died, and was buried. …”
The central part of the Mass is the consecration of the host and receiving Communion. And the Mass itself is central to Catholic life and practice. It makes sense that eating the Bread of Life would be mentioned in the articles of faith in the Creed. By adding those words about the sacraments, we imply the institution of the Eucharist (and all other sacraments)
So can I insert those words? How would the Church go about changing the creed (if it even has the authority to do so)? Like I said, I know the answer is “no”.
