Gratzi!
Jesus conveyed this meaning when He breathed on them to receive The Holy Spirit in them, thus it is God via The Holy Spirit Who is forgiving sins, not the men into whom The Holy Spirit was breathed. As far as I can tell via Scriptures, not a single person since that event of Jesus breathing the Holy Spirit into those Apostles has been so endowed directly by God with us, except perhaps Saul cum the Apostle Paul.
