 Some, however, have given public support.At the 1995 Call to Action conference, for example, the former Bishop of Évreux now titular bishop of Partenia, Jacques Gaillot, popularly nicknamed "The Red Cleric"; the auxiliary Bishop of Detroit Thomas Gumbleton, and theologian Hans Küng (whose authority to teach theology in a Catholic institution was rescinded), were among the featured speakers.Other theologians, such as Charles Curran and Benedictine Sister Joan Chittister are also supporters of the organization.
