Certainly good at making a case.
I can say this.
My mother was in a hospital waiting room when a priest arrived in and sat near her.
He looked very shaken, so she asked him if he was ok.
He told her that he was driving in for the appointment, I believe along a country road, when he experienced somebody trying to steer the car. He said he had a terrible job keeping the car on the road fighting against the force trying to run the car off the road.
On the other hand there's a woman from the Midlands who was in the last stages of MS about 20 years ago who is now walking around in good health.
She was cured in Knock, County Mayo, I have the story from two totally different sources and she is on YouTube, Mary Carroll.
My mother knew her neighbour and I know the priest's brother who was present when she was blessed. I only heard about the priest a few years ago.
