So - we are now refuting the recreation of the last supper/mass.
What about His admonition - Do this in memory of me?
And who says we are now refuting anything? You're the one who made THAT jump right into mass. But no matter, here we go..recreation...memory..actual..real presence..unbloody sacrifice..yet present totally and completely...Go for it. Wherever you want to begin. It's your Catechism.
