Had you read this thread all the way through you would have seen this:
A good, devout Catholic doesn’t need to believe in any of Mary’s miracles to be a Catholic. The Church teaches that private revelation, like these sorts of miracles, can be believed, or not.
You apparently also missed this fact on Our Lady of Guadelupe:
And pointing to Christ? The miracle of the cloak and word of its occurrence spread throughout Mexico and it’s believed that some eight million Aztec natives were converted to Christianity.
Missionaries had been in Mexico for decades with only a few hundred converts but Mary's image on the tilma sufficed to convert 8 million Aztecs. This is not coincidence but resulted from what the Aztecs interpreted about that image. It was quite clear and pointed to Christ!
It pointed them to the Papist version of Christ who, more often than not, could just as easily cast you into hell at the instigation of devils if Mary doesn't constantly protect you from Him:
"One day the King fell seriously ill and when he was given up for dead he found himself, in a vision, before the judgement seat of Our Lord. Many devils were there accusing him of all the sins he had committed and Our Lord as Sovereign Judge was just about to condemn him to hell when Our Lady appeared to intercede for him. She called for a pair of scales and had his sins placed in one of the balances whereas she put the rosary that he had always worn on the other scale, together with all the Rosaries that had been said because of his example. It was found that the Rosaries weighed more than his sins. Looking at him with great kindness Our Lady said: "As a reward for this little honor that you paid me in wearing my Rosary, I have obtained a great grace for you from my Son. Your life will be spared for a few more years. See that you spend these years wisely, and do penance." When the King regained consciousness he cried out: "Blessed be the Rosary of the Most Holy Virgin Mary, by which I have been delivered from eternal damnation!"

Today, Mexico is a country that is not too far removed from pile of you know what status. It's Catholicity has only led to its perpetual stagnation, the dominance of superstition, authoritarian/statist ideologies leading into leftist ideologies, and finally the inevitable breakdown of law and order.
But hey, they're good Catholics eh, much blessed by God?
