I’m a bit late with this post since there’s been so much else going on, but it’s not too late to vote for Macrina the Younger in the first round of Lent Madness.
We studied Macrina in my Early Church History class last semester. My professor used her as an example of possible roles for women in church leadership in the early church. She was an abbess who was greatly revered by her nuns and by the community, and a very strong minded woman. Even before that, she very practically fought against class distinctions in her own home: when she and her mother were the only ones left at home, she convinced her mother to live in the same way that the servants did, and eat the same food.
Her brothers are much better known than she is: Gregory of Nyssa, and Basil of Caesarea, were both bishops and renowned theologians, very active in the Christological debates, and known (along with Gregory of Nazanzius) as the Cappadocian Fathers. Macrina is arguably the Cappadocian Mother.
