Got some sources to back up that fantastically unbelievable claim?
Jeeze it is so steeply versed in lore it is hard to come up with "sources."
Go to Mexico City and see the Manta itself within the Basilica of Our Lady of Guadalupe and go up onto the spot where Juan Diego was given the roses (impossible to get that time of year) and the Manta itself.
As I said, the RCC has beatified (correct spelling this time I hope) and thus has accepted the event as Canon.
The same is true for the appearances of Mary as Our Lady of Fatima, Lourdes and others. She appears historically in very definable places when needed most.
If I was her I wouldn't wast my time appearing today. People are too cynical and detached from God.
