I fear you are right, and you will never get an answer here. MD cannot accept that God gave the Apostles any authority in this matter. To do so would cause his theology to unravel. You see, the ideas upon which his theology is based were founded upon a desire to rejec that authority. Calvin and his peers, during the Reformation, were reacting to the corruption of European clerics. They were trying to find some other source of authority with which to replace them, to purify the faith. They settled on the Scriptures. That bring us to the next reason you cannot get an answer, and that is that MD can never admit that the Church is also “God Breathed”. That would put the Church on equal footing with the Scripture in terms of nature and authority, and his deficient concept of Church cannot tolerate this.
To solve this problem, they have twisted the meanings of the words so that Jesus is just talking about preaching the gospel. That way, they can deny that He gave the Apostles any authority over and above what each believer has.
I forgot to mention, in response to MD wanting scriptural proof of where the disciples “lined up” for confession, that confession was paired with absolution through the priesthood in Lev. 5. The shadow in the OT is fulfilled in the NT.
I don’t imagine “lines” though. It seems that the early Church preferred “crowds”. We see the priestly model again with John’s baptism, where confession was paired with the washing of repentance:
Mark 1:4-5
4 John the baptizer appeared in the wilderness, preaching a baptism of repentance for the forgiveness of sins. 5 And there went out to him all the country of Judea, and all the people of Jerusalem; and they were baptized by him in the river Jordan, confessing their sins.
One has to wonder, how did the listener know that sins were being confessed, if it was not done aloud?
And again we see a similar activity in Ephesus:
Acts 19:16-20
17 And this became known to all residents of Ephesus, both Jews and Greeks; and fear fell upon them all; and the name of the Lord Jesus was extolled. 18 Many also of those who were now believers came, confessing and divulging their practices. 19 And a number of those who practiced magic arts brought their books together and burned them in the sight of all; and they counted the value of them and found it came to fifty thousand pieces of silver. 20 So the word of the Lord grew and prevailed mightily.
How did anyone observing know that they were confessing and divulging their sins, if it was silent?
James 5: 16 Therefore confess your sins to one another, and pray for one another, that you may be healed.
The believers found it most expedient to confess to those to whom Jesus had given the authority on earth to forgive their sins.
The other very important element that is often missed in James is that confession is healing, and confession to “one another” is God’s way of healing our shame of sins.
Don’t hold your breath, Tomster.
