Tonight, at St. Matthew's Cathedral, Archbishop J. Augustine DiNoia, O.P., will be giving the annual John Carroll lecture on "Why Catholics Go To Mass." Archbishop DiNoia, who celebrated his 40th anniversary as a priest this past Sunday at a beautiful Mass at the Dominican House of Studies where he taught for many years, is one of the most gifted speakers in the Church today, a master not only of theology but the English language. His talk will not disappoint. It begins at 6:45 p.m. Archbishop DiNoia is also slated to give the homily at the Red Mass this coming Sunday.
