I have a copy of it that’s much more recent, it continues to be copied throughout the centuries.
Some of the earliest remaining scripture we have dates to the third and fourth century also. Both scripture and icons are copies of copies. To me this doesn’t invalidate them.
But these icons of Jesus and Mary, and the shroud of Turin, etc., are matters for the individual and, as you say, not necessary for our faith; it may be helpful to some and not to others.
For me, my Pantocrator is a likeness of my view of Christ and a means of prayer and constant remembrance. I also have a photo of my deceased mother and she is the most beautiful woman in the world. Perhaps it is just that beauty is in the eye of the beholder.
thanks again..
