"On my knees I beg you to turn away from the paths of violence and to return to the ways of peace....Violence only delays the day of justice. Violence destroys the work of justice...Do not follow any leaders who train you in the ways of inflicting death. Love life, respect life, in yourself and others. Give yourself to the service of life, not the work of death...Violence is the enemy of justice. Only peace can lead the way to true justice."
Pope John Paul II.
He sounds like a Unitarian Universalist to me in this quote.
This is article #9 in a series on Unitarian Universalist Roman Catholicism.
