The Sacrament of Reconciliation (also known as Penance, or Penance and Reconciliation) has three elements: conversion, confession and celebration. In it we find God’s unconditional forgiveness; as a result we are called to forgive others.
So whoever is in Christ is a new creation: the old things have passed away; behold, the new things have come. And all this is from God, who has reconciled us to himself through Christ and given us the ministry of reconciliation ... We implore you on behalf of Christ, be reconciled
2 Corinthians 5: 17-19, 20
