21. I believe in the forgiveness of sins
The glorious mystery in Jesus’ resurrection bring us the the exceptional gift of peace- the first greeting of the Risen One to his disciples-, and the forgiveness of sins announced and given by Christ to his apostles the same day of his resurrection. They are the two sides of the same coin: the gift which brings peace and the peace which arises from the forgiveness of sins.
The forgiveness of sins explains Christ’s mission in the world, as St. Paul wrote: “our Lord Jesus who was handed over to death for our sins and raised to life for our justification.” (Romans 4,25). As a result, peace invade us, because “He is the peace between us” (Ephesians 2,14). Jesus means Saviour: He comes to save men from their sins. In line with that mission, the Lord has apply his mercy with the sinners, because it is necessary to give it to men. For that reason, He wanted to inform his church, and on the evening of the day of resurrection He said to his apostles: “Receive the Holy Spirit. If you forgive anyone's sins, they are forgiven.” (John 20,23). Therefore, the forgiveness of sins exists in the Church thanks to an infinite kindness of God to men.
The Creed of the Apostles practise the forgiveness of sins: “I believe...in the forgiveness of sins.” In the Nicene-Constatinopolitan Creed, it is also stated that: “We acknowledge one baptism for the forgiveness of sins.” We will explain later the importance of baptism in the remission of sin and in the sacrament of penance.
