So the catholic priest has the power to pull Jesus down from Heaven and put Him in a wafer defined by the catechism as ‘truly the real, substantial body, blood, soul and divinity of Jesus Christ’? I don’t think so, and therein lies the basis for dispute. Jesus Himself said that what goes into the mouth comes out through the drought. To get the Life of God in you is not done by ingesting the ‘physical presence of Jesus’. God is Spirit. Wafers are wafers and bread is bread and wine is wine and water is water. To play games of mystery magic and assume powers of magic to call Jesus out of Heaven to the catholic altar is to contradict what Jesus taught in the Olivet Discourse, that He would return TO EARTH, not in the air, at the end of the Great Tribulation. Jesus was so emphatic about His Second Coming to the Earth, setting foot upon the earth, that He revealed the event to John on the Island of Patmos!
It's not by the Priest's power or authority.
