I've always like Mother Miriam, even though, like +Vigano, she's a work in progress. If I recall correctly, she was booted out of the Tulsa diocese for being too orthodox. Not sure where she is now.
I recall about 8 years ago, when driving home from work, I tuned the radio into EWTN, (which is rare because I usually can't stand EWTN), and listened to
Patrick Coffin giving an interview with Mother Miriam. It was quite interesting. They were talking about the sanctity of marriage, and Mother Miriam was defending Church teaching by saying that marriage is only between a man and a woman, and that same-sex marriage is wrong. Well, Patrick Coffin did everything he could to try to distract her onto another topic, including interrupting her, but she wasn't having it. She just talked over him and did a good job of defending Church teaching. I thought that was awesome. Nowadays, Patrick Coffin considers himself to be a Catholic apologist. I don't trust him at all. I'm not sure, but I think she attend the TLM (diocesan, I think).
She is Jєωιѕн, but she is, I believe, a sincere convert. I do think that sincere Jєωs make really good Catholics.
