What was Christ’s commandment to His disciples when He appeared to them after His resurrection?

He said to them, “‘As the Father has sent Me, I also send you.’ And when He had said this, He breathed on them, and said to them, ‘Receive the Holy Spirit. If you forgive the sins of any, they are forgiven them; if you retain the sins of any, they are retained.’” (John 20:21– 23). He gave them this authority to show them that the world always needs repentance and confession so that the believers may never cease to confess the Lord’s blessings as well as the fact that they are sinners and hence offer repentance every time they pray the Lord’s prayer, “Forgive us our trespasses, as we forgive those who trespass against us.” Therefore, Christ who is risen from the dead, calls them to be merciful with the people that the Lord may be merciful with them as well.
