Approbation
(重定向自Approbator)

Approbation is, in Catholic canon law, an act by which a bishop or other legitimate superior grants to an ecclesiastic the actual exercise of his ministry.
The necessity of approbation, especially for administering the Sacrament of Penance, was expressly decreed by the Council of Trent, so that, except in the case of imminent death, the absolution by a priest not approved would be invalid. This approbation for the Sacrament of Penance is the judicial declaration of the legitimate superior that a certain priest is fit to hear, and has the faculties to hear, the confession of his subjects.
