I, for one, greatly appreciate the information you provided as written by Dr. Edward Peters.
This is the first I heard that Schiavo had remarried. I don't know what Catholic priest officiated but to permit him and Jodi Centonze to marry in the Catholic Church may just be a scandalous act, inviting more criticism of the Church.
To go by the Church's stance on this subject, per Dr. Peters, I will go out on a limb and suggest that the Pope must remove the officiating priest from his duties. How else can the Church reclaim it's validity than to address honestly the arrogance of any of it's priests?
Is it possible that the sappy couple simply rented the cathedral and had some other denomination's pastor do the deed?
Canon lawyers are not authoritative. And many Canon lawyers would likely disagree with Dr. Peters.
