Confession is needed but not to a priest. Confession of sin to a priest was instituted by Pope Innocent the III in the Lateran council in 1215. We confess our sins only to God.
JL: If that were true Thebible why then, after His resurrection did Christ breath the Holy Spirit on the apostles with the priestly authority to remit or retain sins?
[Jn20:20 And when he had so said, he shewed unto them his hands and his side. Then were the disciples glad, when they saw the LORD. 21 Then said Jesus to them again, Peace be unto you: as my Father hath sent me, even so send I you. 22 And when he had said this, he breathed on them, and saith unto them, Receive ye the Holy Ghost: 23 Whose soever sins ye remit, they are remitted unto them; and whose soever sins ye retain, they are retained.]
As the Father sent Christ to forgive sins so Christ sends the apostles to forgive sins, a priestly function reconciling those who sin after baptism to God through the Sacrament of Reconciliation (confession).
Forgiving sins is a priestly service as we see in the OT. [Lv5:5 When anyone is guilty in any of these ways, he must confess in what way he has sinned 6 and, as a penalty for the sin he has committed, he must bring to the LORD a female lamb or goat from the flock as a sin offering; and the priest shall make atonement for him for his sin.
Paul speaking of a believer’s sins evidently believed he could forgive the believer’s sins in the person of Christ
[2Cor2:10 To whom ye forgive any thing, I forgive also: for if I forgave any thing, to whom I forgave it, for your sakes forgave I it in the person of Christ;]
[Rms15:16 for my being a servant of Jesus Christ to the nations, acting as priest in the good news of God, that the offering up of the nations may become acceptable, sanctified by the Holy Spirit.] YLT
