The Knights of Columbus are sponsoring a “Blue Mass” at 7 p.m. Thursday, Sept. 17, at Holy Angels Catholic Church in Aurora in honor of first-responders throughout the area.

The Blue Mass, referring to the blue uniforms worn by many public safety personnel, dates back to 1934, and is a venerable tradition in many dioceses. Although it is a celebration of a traditional Catholic Mass, the event itself is nondenominational and all are invited.

“This Mass calls forth in us a greater awareness of, and gratitude for, the lives of those who serve and protect us so faithfully,” Simmons said. “In previous years, we have had representatives from several area departments, including Aurora, Oswego, Montgomery, Kane County, Aurora Fire Department and the Illinois State Police.”
