Jesus told the Christians to confess their sins to each other ( and not that they should confess to priest/minister ) and so, after a person has become a Christian, after they have baptized, having surrendered completely, some write their confessions. Disciples tell the story of the writer: typically, from the age of awareness to the time of the confessions. Disciples can also be updated every five or ten years, or at longer intervals. Confessing sins is not a requirement ( a law ) in Jesus’ doctrine. It is not like baptism, which is a prerequisite to salvation.
James 5:16 Therefore confess your sins to each other and pray for each other so that you may be healed. The prayer of a righteous person is powerful and effective.
Nowhere in the Gospel Jesus tells us that a priest can mediate between men and God to obtain remission of sins for a subject. This would render ‘Baptism’ useless! It is another method to control, invented by the Catholic church, to trap stupid people.
Jesus is the only mediator between you and God: nobody else!
TI1 2: 5 For there is one God, and one mediator between God and men, the man Christ Jesus;
TI1 2: 6 Who gave himself a ransom for all, to be testified in due time.
JOH 3:5 Jesus answered, Verily, verily, I say unto thee, Except a man be born of water and of the Spirit, he cannot enter into the kingdom of God.
