Impanation

n.
  1. Embodiment in bread; the supposed real presence and union of Christ's material body and blood with the substance of the elements of the eucharist without a change in their nature; -- distinguished from transubstantiation, which supposes a miraculous change of the substance of the elements. It is akin to consubstantiation. (Eccl.)
