However, is it not clearly stated in the scriptures, man does not have any power, or the right to forgive any person of their sins?
No, authority to forgive sins (in the lord's name) is clearly stated in the risen Lord's commission to the apostles (John 23):
[Jesus] said to them again, “Peace be with you. As the Father has sent me, so I send you.” And when he had said this, he breathed on them and said to them, “Receive the holy Spirit. Whose sins you forgive are forgiven them, and whose sins you retain are retained.”
