I like her because she seems to be a mature woman who some people say might have had a family. So she might have been a woman who would understand the problems and concerns of someone in the outside world. I read once that there is speculation that perhaps her family died in the Black Death that swept England during her lifetime. That would mean she knows how it feels to lose a child, like I do…
I also like that she was separate from the world, yet participated in it. She might have been an anchoress yet she was available on a daily basis to give counsel to whom ever asked it of her.
I also like her theology. The visions she had and wrote down ( possibly learning to read and write for this very purpose) were very much about the “mother” like nature of God and Jesus. In other words, the nurturing side of God rather than the punitive. It was a rather unusual way of looking at things for her time, and indeed for our times.
Can you have the Virgin Mary as your saint in a particular guise? Her visitation at Walsingham, England was the first apparition of Mary and holds much the same interest for me.
