Adessenarii or Impanators, a sect in the 16th century, who believed in the real presence of Christ in the Eucharist, but not in the full Roman dogma on that subject. The name is derived from the Latin word Adesse, "to be present." They held the so-called doctrine of impanation, scil. "non adesse in Eucharisti Humanam seu Carneum Christi Corpus sumptum ex B. Virgine Matre sod Corpus panaceum assumptum a Verbo." SEE IMPANATION.
