Some really stupid writing
The first words the vision said were "Don't be afraid, I won't hurt you."
It is my biggest peeve with a lot of writing in film and television. .
Somehow I doubt that if the Virgin Mary appeared to anyone and spoke to them in any language, contractions like "don't" and "won't" would not included in the vocabulary had it been English. The line should have "Do not be afraid, I shall not hurt you."
It has happened in the Star Trek shows with English speaking Kingons and Vulcans, it has happened in some of the Biblical themed films from the 1950s etc.
Again, just a peeve of mine.
