"See that sins are forgiven through the Holy Spirit. But men
make use of their ministry for the forgiveness of sins, they
do not exercise the right of any power of their own. For they
forgive sins not in their own name but in that of the Father and
of the Son and of the Holy Spirit. They ask, the Godhead gives,
the service is of man, the gift is of the Power on high."
Jerome (Stridon, 345-419), Letters, No. 14, ML 22, 352
"Far be it to censure the successors of the apostles, who with
holy words consecrate the body of Christ, and who make us
Christians. Having the keys of the kingdom of heaven,
they judge men to some extent before the day of judgment,
and guard the chastity of the Bride of Christ."
