Jesus delegated to the Apostles and successors - Go Preach and Baptize and forgiveness of sins.
Show me where Jesus stated that sins are forgiven directly?
1Tim 2:5-6
Again, our mediator is not anybody other than Jesus Christ. Those who attempt to mediate for Him become antiChrist or a counterfeit substitute for Christ.
We are each part of the royal priesthood during the Church Age. The High Priest is our Lord and Savior Christ Jesus, through whom we all have access to God the Father when in fellowship with Him.
