PORTLAND — Maine’s Catholic diocese paid tribute to police, firefighters and paramedics during the church’s annual “Blue Mass” Sunday.

Monsignor Marc Caron gave thanks and bestowed his blessings on Maine’s emergency responders during Sunday services at the Cathedral for the Immaculate Conception in Portland.

Members of public safety agencies attended the Mass in uniform. Color guards were on hand and the Maine Public Safety Pipe and Drum Corps performed outside the church before and after the Mass.

The event takes place each year on the weekend closest to Sept. 11 in recognition of the response to the terrorist attacks 11 years ago.
