Pope Paul VI is the topic at 7 p.m. Tuesday, April 9, at St. Mary Cathedral's lower center as Father John Tuohey speaks on the man he calls "the implementation pope." It was Paul VI who continued the Second Vatican Council after the death of John XXIII and began the difficult task of putting the council's teachings into action. Father Tuohey is the ethicist for Providence Health and Services.

This talk, originally scheduled for the previous week, now replaces a session that had been planned to discuss liturgy and worship since Vatican II. There will be no presentation on April 2.
