Antoine, from all our past discussions, it seems to me that you must be one of the more recent moderate voices from the Vatican that really would like to reconcile Catholic Faith with evolution, BUT the current powers in control are still the intrenched Fundamentalists. They evidently still want the average Catholic (not trained in philosophy) to believe that Adam was a single human being, created sinless and destined to remain that way if not operated upon by outside forces to rebel. This is how I interpret the passage from Humani Generis (#37) which, I presume, still remains operative in the current Catholic catechism:
….the sources of revealed truth and the documents of the teaching authority of the Church proposed with regard to original sin which proceeds from a sin actually committed by an individual Adam in which through generation is passed onto all and is in everyone as his own” .
I am certainly not going to live long enough to see your views taught to youngsters in first grade in St. George parochial school. In the meantime, I wish you the good Lord’s blessings in your work
