There may be no miracles per se but what are the criteria for miracles? It seems to be being healed of a health problem. But there are other problems, alcoholism and so on. In any age, it's difficult to really classify miracles unless it is something extremely obvious.
I would have to go there myself to really, really decide. Friends go there, I"m neutral and I think it seems both sides go overboard. Cardinal Sarah spoke at last Summer's Medjugorje Youth Festival. You really can't have it both ways and say, I like when he says this but reject other... well you can. But I'll patiently wait... also, believe it or not, the recently approved (2008) apparition of Laus saw Our Lady appearing from something like 1664-1718, so yes, there does seem to be precedent for apparitions appearing over a number of years.
She told confidents the date of her death, really, she's a bit like St. Padre Pio, was able to do a few different things (including prophecy, maybe bilocation too) and it's hard to find a place more devout to the Catholic faith than Poland though, full respect to some other countries as well.
You Protestants don't understand Our Lady of Guadalupe was Aztec. They are not carving out hearts there. What an ignorant comment. There are Polka Masses. Trads are poisoning discussions.
This looks like a celebration for Our Lady of Guadalupe, December 12th and guess what? Juan Diego was Aztec and was not OLG dressed like an Aztec? Maybe there is more to the story here. Does that make this okay in Church? No, not really to me but there would seem to be a reason as to why this happened.
