* In Summary it says that we must confess our sins to God (1 Jn 1:9). We are to confess to 'one another' in the presence of the presbyters (priests)(Jas 5:16). The OT prepares us for the process of confessing to priests (Lev 5:5-6). We see that Christ has the authority to forgive sins (Mt 9:6-8), gives the authority to his disciples (John 17:18, John 20:21-23) who now are ambassadors for this ministry of forgiveness (2 Cor 5:18 -21)* Listen to the Bible study on the biblical basis for the sacrament of Confession.
