Paul F. Knitter is the Paul Tillich Professor of Theology, World Religions and Culture at Union Theological Seminary in the City of New York. He was formerly Emeritus Professor of Theology at Xavier University in Cincinnati, Ohio. Since publishing his book, No Other Name? (1985), Knitter has been widely known for his religious pluralism. Along with his friend and colleague, the Protestant philosopher of religion John Hick, Knitter came under criticism from the then Cardinal Ratzinger (who later served as Pope).
In 1984 he was one of 97 theologians and religious persons who signed A Catholic Statement on Pluralism and Abortion, calling for pluralism and discussion within the Catholic Church regarding the Church's position on abortion.
Knitter holds a licentiate from the Pontifical Gregorian University in Rome (1966), as well as a doctorate from the University of Marburg, Germany (1972).
