Okay, I read your whole article word-for-word. I've also read Marcus Borg's "Convictions." Just three questions...
1) Is it your position that the concept of substitutionary atonement (I'm not talking about the term, but the concept) wasn't conceived of or taught (in any way) by Jesus and his apostles in the first century?
2) Do you accept the Gospel of John as authentic?
3) Which of the epistles attributed to Paul do you accept as authentic? (Does that list include Romans and I Corinthians?)
I look forward to your answers.
All the best!
