The Hidden Life of the Holy Family

Wow.. you must watch these videos on The Hidden Life of the Holy Family! There are two and I just watched the first one.
Fr Chris mentioned something about St. Faustina being made a doctor of the Church and the first thing, and I'm not sure why, that popped in to my head at that moment was, could this be the major event in the Church during which the Warning or was it the Great Miracle, could happen? It struck me so out of the blue that I was amazed myself.
Thoughts?
