II. Why a Sacrament of Reconciliation after Baptism?

From The Catechism of the Catholic Church

1425
“YOU were washed, you were sanctified, you were justified in the name of
the Lord Jesus Christ and in the Spirit of our God.”⁹ One must
appreciate the magnitude of the gift God has given us in the sacraments of
Christian initiation in order to grasp the degree to which sin is excluded for
him who has “put on Christ.”¹⁰ But the apostle John also
says: “If we say we have no sin, we deceive ourselves, and the truth is
not in us.”¹¹ and the Lord himself taught us to pray:
“Forgive us our trespasses,”¹² linking our forgiveness of one
another’s offenses to the forgiveness of our sins that God will grant us.
