I did. I prayed to God when I had certain moments of doubt when I was in my twenties. I unnaturally at 600pm went to bed. I just felt tired. I never did that at the time. I fell into a deep sleep. I woke up at 2:15am then just put on the tv. It was set to Ny channel 9 WOR which had a Documentary on the Shroud. As the narrator spoke I sensed the Holy Spirit. The man talked about the suffering this man went through with the wounds on his body. I had the greatest supernatural presence ever as the man spoke. I had a series of things happen after this event. Amen!! Praise Jesus.
Bless you. God spoke to you through the Shroud. I didn’t take related supernatural experiences into account in my comment!
Still, I don’t think many Catholics’ continuing faith is contingent on the authenticity of any one particular relic.
