If the Eucharist actually becomes the body and blood of Christ during the mass, then what’s the white wafer the priest holds up?
That doesn’t look like flesh and blood to me as you claim it becomes during the mass.
"My Jesus! What a lovable contrivance this holy Sacrament was - that You would hide under the appearance of bread to make Yourself loved and to be available for a visit by anyone who desires You!" - St. Alphonsus Ligouri. [emphasis; mine]
