Libelli Pcenitentiales
From BiblePortal Wikipedia
Libelli Pcenitentiales [1]
(certificates ofpenitence), documents frequently issued during and after the 8th century by the Romish priesthood, granting immediate absolution to those who confessed their sins to the priest, and declared themselves ready to fulfil the appointed penance, even though they were not prepared to partake of the communion. Great opposition was made to this practice by the reformers in the time of Charlemagne. (See Penitential).
