My mother and father always urged us to stay away from apparitions without ecclesiastical approval or permission. My father would say that there was enough in the apparitions at Knock to inspire our contemplation for the rest of our lives. He and my mother said this also was true of the apparitions of Our Lady of Soufanieh in Syria.
I would love for Father Sudac to be a true mystic, but I only have a gut instinct that says "Keep your distance."
As Father Benedict Groeschel says, "If you want a miracle, go to Mass. If you want a message, read the Bible."
