John 6: Bread of Life Discourse

In the "Bread of Life Discourse", Jesus introduces the

Transubstantiation

Definition of Transubstantiation

The Council of Trent summarizes the Catholic faith by declaring: "Because Christ our Redeemer said that it was truly his body that he was offering under the species of bread, it has always been the conviction of the Church of God, and this holy Council now declares again, that by the consecration of the bread and wine there takes place a change of the whole substance of the bread into the substance of the body of Christ our Lord and of the whole substance of the wine into the substance of his blood. This change the holy Catholic Church has fittingly and properly called transubstantiation." (CCC 1376; emphasis added)

Etymology of transubstantiation

  • from: trans- = across, beyond + substance ("what it is") (-tion = makes a noun)
    • trans- = across, beyond
    • substance = sub- (up to, under, made up of) + stare (that which stands, what is)
      • stare has PIE root *sta- "to stand, make firm, be firm"

transubstantiation versus transformation

  • trans-substance = changes form but not substance
  • trans-form = changes its appearance while keeping its substance
    • ex. water keeps its substance while changing form when solid, liquid or gas
  • transform = trans- (across) + form (image, likeness, shape, appearance)
    • i.e., change in shape, appearance

belief in transubstantiation

"Amen, amen, I say to you, whoever believes has eternal life. 

I am the bread of life. 

Your ancestors ate the manna in the desert, but they died, 

this is the bread that comes down from heaven so that one may eat it and not die.

I am the living bread that came down from heaven; whoever eats this bread will live forever; and the bread that I will give is my flesh for the life of the world.”
