Jesus entrusted the ministry of reconciliation to the Church. The Sacrament of Penance is God's gift to us so that any sin committed after Baptism can be forgiven. In confession we have the opportunity to repent and recover the grace of friendship with God. It is a holy moment in which we place ourselves in his presence and honestly acknowledge our sins, especially mortal sins. With absolution, we are reconciled to God and the Church. (USCCB)
“Let us recognize once more the primacy of grace and ask for the gift to realize that Reconciliation is not primarily our drawing near to God, but his embrace that enfolds, astonishes and overwhelms . Yet it is not so much that we go to the Lord, but that he comes to us, to fill us with his grace, to fill us with his joy. Our confession gives the Father the joy of raising us up once more. It is not so much about our sins as about his forgiveness. Think about it: if our sins were at the heart of the sacrament, almost everything would depend on us, on our repentance, our efforts, our resolves. Far from it. The sacrament is about God, who liberates us and puts us back on our feet.” (Pope Francis)
