A Blue Mass will be celebrated at the Cathedral of the Assumption, 433 South Fifth St., on Sept. 12 at 7 p.m.

The Mass is intended to give thanks for the work of current and former first responders and pay tribute to those who lost their lives in the line of duty, a news release from the Cathedral of the Assumption said. Father Martin A. Linebach, vicar general, will preside.

“The Blue Mass allows us to honor heroes in our community — the women and men who put themselves in harm’s way daily to serve, protect and defend us,” said Maggie Cyphers, director of worship at the Cathedral.

All people who work as first responders are encouraged to attend.

Drum corps and bagpipe players from local first responder agencies will be on hand. An honor guard will also perform ceremonial duties.

Representatives of the Louisville Metro Police Department, Louisville Fire Department, Louisville Emergency Medical Services and the Jefferson County Sheriff’s Office are expected to attend.

The Mass is open to the public; there is no need to make reservations. Agencies that wish to participate formally in the event may contact Cyphers at 657-5222 or mcyphers@cathedraloftheassumption.org.
