Father Gustave Weigel has been a close observer of the Protestant scene for a number of years. He has given considerable attention to Protestant theology and to ecumenical problems, and his review of the first volume of Paul Tillich’s Systematic Theology is considered one of the best written to date. A Jesuit, Father Weigel taught for six years at the Catholic University of Chile. He taught ecclesiology at Woodstock College in Woodstock, Maryland.
