But doesn't the Church do a rigorous investigation to test whether miracles are fake, from the devil, or from God? If these supposed miracles are from the devil but the Church claims they are from God, then how can we trust all the other times when the Church has declared something being miraculous? I read somewhere that a blind man was healed of his sight 90% but that the Church did not use that as one of the miracles because it was not a complete healing. And if a person is cured of cancer, the Church waits 4 years before determining whether it was a miracle or not - to see if the cancer came back.
If we do not take the Churches word that these are true miracles from God, then why take it's word on anything it has every made an investigation on to determine whether something is from God or the devil (whether it be an apparition, miracle, or other)?
