"All change, except away from evil, is the most dangerous of all things". (Plato)
This name change idea will never get anywhere, the few people proposing it, Fr. Purdy and like two Philippino woman, are just three nobodies who think they discovered something they can make a "mission" of, it is rooted in ignorance and pride. Likely because they previously thought that the apparition was about worldly success. That their mission is misdirected from the get go, clearly shows that it is wrong. That they chose the Spanglish title of Our Lady of "Buen Suceso" of the Purification says it all, they are misdirected at their first baby step. It'll never get anywhere, Catholics seeking truth do not follow the blind, they follow the voice of Our Lord.
Here is what they should have done: teach to the few simple minded people like them, that the English title of "Good Success" does not mean success in the sense of worldly gain. That is all.
My wife has a big devotion to our Lady of Good Success and has read the books in English, the thought that Our Lady of Good Success has to do with worldly success has never entered her mind. I read the books too, and the thought never entered my mind. The attraction to me has always been the message about the future, which in every way appears to describe our times. I first learned about Our Lady of Good Success in Catholic Family News, I think in the late 1990's, they referenced the books by Tradition in Action. The articles were all about the message about the future.
