Not Peter, Our Lord:
After his resurrection, Christ also gave the apostles the power of forgiving sin when he breathed upon them saying "Receive the Holy Ghost; who soever's sins you forgive they are forgiven, who soever's sins you retain, they are retained" (John 20:21-23). So now the Priest forgives sins not in his own name but in the name of Christ.If you are at all interested in Scripture, read Acts 6:6, 14:22, 20:28, 1 Tim 4:14, 2 Tim 1:6, 1 Cor 4:1, Heb 5:1.
Of course if the word VICAR is confusing, Holy Scripture may be a hurdle. On the other hand there is at least one priestess here who claims to know what all words mean, maybe we will get lucky and she will descend from her high place and actually answer simple questions. Or not.
You failed to offer scripture in support of your foolish argument, but the idiotic delusion of men.
FAIL!
