Bishop Cahill will celebrate the Diocese's first "Blue Mass" in the Cathedral at 6:30 p.m. on Tuesday, September 29 (Feast Day of St. Michael the Archangel) to honor our public safety personnel in the Police, Fire and Sheriff's Departments. Families of these departments are also invited to attend. The Mass will be live-streamed at www.olvcathedral.org for those unable to attend and for all others wishing to tune in for the Mass.
