St. Francis could be seen as a Catholic Left, because he showed kindness to Animals, despite the fact that most orthodox theologians such as Augustine and Aquintas believed that animals had no souls.
Pope John Paul II could also be seen as a Catholic Left, because he apologized for the burning of heretics, the Crusades, and false heresies such as the Gallileo "Heresy". He also enforced dialogues with other world religions.
St. Julian of Norwich could also be seen as a Catholic Left, considering she had a vision of Jesus who explained that there was a higher purpose of hell for redemption, and that in the end, all will be well.(She asked about those who never heard of Jesus). Many scholars believe she was a Universalist.
