In addition to her support of abortion, Sr. Donna Quinn has publicly attacked the Catholic Church. According to Lifesite News:
In a 2002 address to the Women's Studies in Religion Program at Harvard Divinity School, Sr. Quinn described how she came to view the teachings of her Church as "immoral": "I used to say: 'This is my Church, and I will work to change it, because I love it,'" she said. "Then later I said, 'This church is immoral, and if I am to identify with it I'd better work to change it.' More recently, I am saying, 'All organized religions are immoral in their gender discriminations.'"
Quinn called gender discrimination "the root cause of evil in the Church, and thus in the world," and said she remained in the Dominican community simply for "the sisterhood."
