The act of confession is something Protestants often fail to understand.
“The Sacraments of Penance and Reconciliation […] flow directly from the Paschal mystery…In fact, the same evening of Easter the Lord appeared to the disciples, closed in the Cenacle, and, after addressing to them the greeting ‘Peace be with you’, he breathed on them and said: ‘Receive the Holy Spirit. If you forgive anyone’s sins, their sins are forgiven.’”
I wanted to highlight that quote because it stands out to me personally. More later.
