Jesus healed on the Sabbath and the Pharisees said the same thing to Him.
Imagine that.
Knowledge of Scripture has never been a Catholic strong point.
Two points 1) Catholics have the entire Bible, not the Readers Digest version ordered made by a sodomite that was into Wiccan.
2) This IS My body... This IS My blood....seems pretty clear to anyone that can read. It is not the mysterious, veiled, blurred comments the prots like to make it out to be.
More than that: In the healing of the blind man... There is a specific Pharisaical injunction against spitting upon earth on the Sabbath, because that supposedly made mortar, and was considered work... It was not the healing only, but the method. Yeshua stuck his finger in the Pharisees' eye every chance he got. Once one researches a bit, it becomes almost comical in the ways that Yeshua directly opposed tradition.
