In the article Wilhelmina is related to have said she wanted to write a novel like Little Women, which was a revolutionary feminist work by a transcendentalist heretic.
Certainly there are many aspects that seem miraculous but I'm wary of being duped by the Novus Ordites.
There are lots of unsavory red flags, but, like you say, this does not rule out a Divine suspension of the laws of nature.
I am of the ever more firm opinion that this is not about Sister, per se. If it is a Divine manifestation, then it is a sign, not of one woman's sanctity, but relating to where we are on the timeline. And as such, I look for more signs to come.
I expect more signs, if this is indeed a "sign of the times."
It is possible that this is a herald that the 5th Age is finally coming to its miserable end.
Secondly, Drolesky makes some good points about the spectrum (read:journey) participated by every soul. Many of us started out in the novus ordo and worked our way radical. If I were run over by a car while still in the novus ordo, I might still have saved my soul, because my soul was indeed on fire even then.
The point is that I have no problem believing this woman saved her soul. I do have a serious problem, however, in believing that God is trying to get our attention so that we may look at this particular Catholic life. No, no, no! We are to look for Him in this thing! We are not to allow ourselves to be distracted by looking too closely at her, except inasmuch as the facts of her case point to more universal realities about Faith and the Church.
