Hi,

I want to help you understand. The appearance of the bread and wine don't change, they remain the same but the substance does. The bread and wine become Jesus, His body, blood soul and divinity. The risen presence of Christ. Your comment saying it is cannibalism isn't true.

This is God's plan, His desire. You can't keep saying no.
The Protestant messengers are hearing these words from
Heaven, read the bolded.

Faith is so important, accepting this gift of God in Us, even
though we don't see a change! We are taking God's Word.
Jesus said it many times in the Gospel. Recognize he Manna in the desert is a 'type' prefiguring the Holy Eucharist.
One reference, there are many in John 6, it would John 6:54.

God is going to show you personally at the time of the Great Warning.
