\Im"pa*na"tion\, n. [Cf. F. impanation. See
{Impanate}, a.] (Eccl.)
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.
