There are no new ideas in this installment. The symmetry with Genesis 3 is, of course, noted as early as in St. Justin Martyr. I did not want to fast-forward to the dealings with the devil that are going to come up next.
I am sure you are correct. But this is what I was referring to:
"And so also was it proper that the devil, who, being man's tempter, had conquered him in eating of the tree, should be vanquished by man in the suffering of the tree which man bore.
By the way, I agree with your comment about the symmetry; nothing “unorthodox” about that.
