Dear David:
Prior to your own post, I scoured your website to find the answer to this “interesting” question but found none. Even Miranda’s site does not (or inadvertently fails) to dwell on this.
Thus, my own wild speculation.
Assuming that His Holiness, Pope John Paul II, resigns I think he should be at most referred to as “Pope Emeritus.” I know this could be the first time that this term is used but there is always a first time! ( A retired Eastern Patriarch is called “Patriarch Emeritus.”)
A Cardinal is
created by decree of the reigning Pope. Conversely, a Cardinal should be subject to “uncreation” only by that original Pontiff. Since Pope Paul VI created Karol Wojtyla a Cardinal back in 1967 and Pope Paul VI is now deceased, Pope John Paul II remains a Cardinal at the very least.
Whereever he chooses to reside (active or retired), a Cardinal is not subject to the jurisdiction of the local ordinary. He remains subject only to the reigning Pope. However, he could be subject to the “rules” of a monastery if he so decides to enter into a monastic life.
Section 2 of Canon 332 of the Latin Code of Canons provides that: “. . .Should it happen that the Pope resigns from office, it is required for validity that the resignation be freely made and properly manifested, but it is not necessary that it be accepted by anyone.” The Latin Code does not specify who determines that the resignation is “freely made and properly manifested.”
Very interesting. . .
