The first Protestants of the Christian Era appear in the Book of John. In John 6:33, Jesus told His followers “If you do not eat My Body and drink My Blood you do not have life in you.”
“Huh?” they said. “What’s that mean? Must be symbolic of something. Let’s find out.”
But, Jesus just repeated “If you do not eat My Body and drink My Blood you do not have life in you.” It became apparent that He was serious. He said, and reinforced, a dozen times, “If you do not eat My Body and drink My Blood you do not have life in you.”
The first Protestants of The Christian Era got up and left, announcing “This is intolerable!” as they abandoned Him. They believed in the common standards of Conventional Reality, rather than in Jesus. In every generation, that is the most widespread violation of The First Commandment.
Soon, only the 12 Disciples remained. They did not love their self-righteousness more than Jesus.
Afterwards, at The Last Supper, Jesus changed bread and wine into His Body and Blood. He provided The First Holy Communion to those in attendance so that those who believe and obeyed could “have life in you”.
In every generation’s ration of genes, His words “If you do not eat My Body and drink My Blood you do not have life in you.” separate Protestants from obedient Catholics.
Catholics understand that His bizarre Separating Instruction operates in every generation. Jesus used His power to establish One Church with a priesthood He Ordained with the authority to forgive sins and bring about The Miracle of Transubstantiation. He did that to let each person, in every generation, freely choose to do, or not do, what is necessary to “have life in you.”
Protestants, in the conflicting confusion that’s unavoidable in the 43,000 denominations that have come and gone in the last five hundred years, lack that historical perspective.
The need to obey His Great Separating Instruction is as it was 2,000 years ago. Only those who receive His Body and Blood have “life in” them. Better to be on the road than in the ditch!
