What part of reading and singing Scripture texts, saying some prayers, and offering the bread and wine using the exact words related in the Gospels do you feel is somehow in contradiction to the Gospels?
Have you ever actually attended a Mass (and paid attention to it) in your life?
The part where the priest calls Christ down from Heaven and renders Him present on the altar as per O'Brien in The Faith of Millions.
That you have to partake of the Mass to be saved in contrast of Jesus saying we are to believe in Him.
For starters.
Yes I have attended a Mass at a wedding if that counts. Did not participate.
