Men twisted, at the inveigling of the evil one, the truth of Christianity into the dogmas of caatholicism long before Luther showed up. Your blasphemous the real Christ in the wafer on the catholic altar arose centuries before Luther awoke to the heresies taught by caatholicism. The worship of the Mother of Jesus as an assistant to help Jesus accomplish His Priestly duties arose to full heresy after that, however.
Transubstantiation is not blasphemous at all.
It is a re-presentation of the Last Supper.
Haven’t I told you this before?
Luther believed in the Real Presence, and Luther had the exact same devotion for Mary than any Catholic has. Luther would have burned you at the stake for denigrating the Real Presence.
