I prefer to believe.
That is all.
In the case of the shroud, belief without basis is not necessary. The thing is basically a photographic negative created at a time prior to photography being invented on the planet...
The image on the Shroud is almost photographic in nature. That indicates an instantaneous phenomenon. The body's image was captured on the Shroud the microsecond before it left this mortal coil. All subsequent appearances of Christ were not of this Earth. Or of this dimension, I speculate.
Man can only hope to comprehend what took place that morning. In no way can we hope to know by what process it was done.
Who was it who said, “I believe, so that I may know”?
