On September 11, parishes may wish to celebrate a special Mass for “first responders” – such as police officers, firefighters, and emergency medical technicians/paramedics – using the Mass for Those in Public Office (#22) or the Mass for the Preservation of Peace and Justice (#30). Appropriate intercessions could also be included at the Sunday Masses on the weekend of September 9-10. https://www.usccb.org/resources/september-11-patriot-day
