I cannot recall all the details, but more than ten or twenty years ago, there was a so-called Marian miracle, where the woman or seer involved was able to get the statue to cry tears of blood.
A priest exorcist heard about this from the bishop of the diocese and volunteered to interview the woman and perform the required exorcism.
The priest had the statue brought into the rectory office, and then asked the woman (seer) to meet him in the rectory. She agreed to do so.
She was asked to kneel down before the statue and the priest stood watching and praying behind her so that she could not see what the priest was doing.
After "praying" devoutly for about thirty minutes, she said that the power she had over the statue had vanished and that she was not able to get the BVM to cry tears of blood upon demand. Unbeknownst to her, the priest had been praying prayers of exorcism to block the devil and/or any black magic.
The exorcism was very effective, and finally the woman confessed that she was using some kind of black magic.
Then there is this incident. Is it related? We cannot trust miracles, nor can we trust false prophets and those who claim to be Christ.
