“For neither is the Son, (inasmuch as He is equal to the Father), seen by anyone other than the Father, other than by the Holy Spirit. So, all those who saw the Lord Jesus Christ according to his humanity, and did not see and believe according to the Spirit and the Divinity, that He was the Son of God, were condemned.
In like manner, all those who behold the Sacrament of the Body of Christ (in the form of bread and wine, which is sanctified by the word of the Lord) upon the altar in the hands of the priest, and who do not see and believe according to the Spirit and Divinity that it really is the most holy Body and Blood of our Lord Jesus Christ, are condemned.. The Most High having declared it when God said, “This is My Body, and the Blood of the New Testament,” and “those that eat My Flesh and drink My Blood have everlasting life.”
No-one can see God, but Christ who is the eternal image of the Father and those who see him in his fleshly/ earthly body see the Father.
Now here is the crunchy part: – If when you see the Host after it has been sanctified at the hands of a priest at the altar and you do not see and believe according to the spirit that it truly is the Body and Blood of Our Lord Jesus Christ you are condemned. “The Most High having declared it when God said, “This is My Body, and the Blood of the New Testament,” and “those that eat My Flesh and drink My Blood have everlasting life.””
The fourth Lateran Council occurred in 1215, well within St Francis’ lifetime, it was there that the concept of transubstantiation was used in conjunction with the change taking place in the elements of the Eucharist, known though not officially defined.
Francis, however is far more concerned that we see Jesus in the Flesh in the Eucharist with our spiritual eyes just as the Apostles saw his Body and Blood with their spiritual eyes in his flesh.
Necessary for salvation St John tells us: “John 6:54-59”
If the Eucharist is hostage will we perish?
