The Pieta is amazing. But regarding all of the other narrative, I don’t really understand it. And I went to Catholic school for 12 years! My wife also went to Catholic school for 12 years, but neither of us really understood all of this. We had a lot of kids though, but they each went their own way when it came to religion. The whole Catholic thing pretty much was too much.
The Sorrows of the Blessed Virgin Mary are all in the Bible.
I think that our own family sorrows mirror hers.
