Correct. The point was merely an used allegorically to prove a point. Those Catholics who are unfamiliar with approved Marian apparitions and the Church's process for approval or disapproval should not be "slammed" for questioning them. Even if it is approved, theologically, a Catholic is NOT bound to hold to it. However, that does not mean that they should not believe it, nor that it might be beneficial for the proper understanding of objectivity, world view and faith. Normally, approved Marian apparitions, if understood properly, will enhance one's faith and world view. My point is that some of the things surrounding the stories of apparitions may or may not be historically accurate. I personally believe Dr. Drolesky's article is a masterpiece. However, I don't expect all Catholics to understand it nor agree with it. We should carefully and charitably point them to authoritative Church teaching that confirms Christ's kingship and Mary's Queenship.
You didn't ask me, but I believe the church given it "worthy of belief" status.
Let's face it. If it turns out not to be true, what will that do to the millions who revere this icon?
Best leave well enough alone, I suppose. History tells us what happened in the Russian Orthodox church when they tried to correct an historical mistake.
