You ignore the verse in which Jesus says to the apostles:
“Receive the Holy Spirit. Whose sins you shall forgive, they are forgiven them, and whose sins you shall retain, they are retained.”

How can the apostles conceivably discern which sins to forgive, and which to retain, if they have no knowledge of those sins? Therefore, Jesus logically implies that people will TELL the apostles their sins.
It seems incredible that you would not have quoted such a relevant verse.
I don't know why you'd find it incredible...There's not a single word/example about such a practice taking place in the scriptures...That would lead one to believe that the verse doesn't quite mean what you guys want it to mean...Especially since this breathing the Holy Spirit was something given to all the disciples, not just the apostles...
