During his homily on March 22 at morning Mass in the Domus Sanctae Marthae, Pope Francis spoke about the role priests play during the weekly confessionals, a tradition of the catholic church.
As reported by the Catholic Herald, the Pope reminded people that when they go to confession, “please, let’s not think that we are going to the dry cleaners to get a stain out. No. We are going to receive the loving embrace of this faithful God who always waits for us. Always.”
This teaching specifically introduces a third party to the prayer between you and God, a third party who is a human, a sinner.
The Bible is clear on this
Act_4:12 Neither is there salvation in any other: for there is none other name under heaven given among men, whereby we must be saved.
Jesus himself was accused of blasphemy for forgiving a man of his sins.
Mat 9:2 And, behold, they brought to him a man sick of the palsy, lying on a bed: and Jesus seeing their faith said unto the sick of the palsy; Son, be of good cheer; thy sins be forgiven thee.
Mat 9:3 And, behold, certain of the scribes said within themselves, This man blasphemeth.
Mat 9:4 And Jesus knowing their thoughts said, Wherefore think ye evil in your hearts?
Mat 9:5 For whether is easier, to say, Thy sins be forgiven thee; or to say, Arise, and walk?
Mat 9:6 But that ye may know that the Son of man hath power on earth to forgive sins, (then saith he to the sick of the palsy,) Arise, take up thy bed, and go unto thine house.
Blasphemy is a man claiming to forgive sins or to hear your confessions on behalf of God.
