In a discussion of whether science can prove/disprove transubstantion, Carson said: He was alleging that transformation can be proven or disproven by science but transubstantiation cannot. This, however, is not true. Notice the difference between the two. Transubstantiation says that the substance of the bread and wine is completely replaced by the substance of Christ, only the outward visible form (species) of the bread & wine remains. Transformation would mean that the outward visible forms (species) change to that of Christ's body and blood but that the substance of the bread and wine remains. Transubstantiation, therefore, could be scientifically proven if it were true. It could be ascertained whether or not the substance of the bread was altered and completely replaced by the substance of flesh or not. Carson says: DNA can be detected, and the difference between wheat DNA and human flesh DNA can be detected.
