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"

• trans-substance = changes form but not substance
• trans-form = changes its appearance while keeping its substance

  • i.e., change in shape, appearance
