Heroic firehouse chaplain who died of 9/11-related cancer honored by FDNY at event for bravest lost this year

He put out emotional fires.A heroic firehouse chaplain who died of 9/11-related pancreatic cancer was honored at a heartfelt FDNY ceremony Wednesday — with co-workers praising his selfless ability to comfort bravest families on the worst days of their lives.Rev.Monsignor John Delendick, of Ladder 170 — who buried hundreds of fallen firefighters over nearly three decades  — was one of 14 FDNY members who died last year, officials said at the department’s annual Memorial Day Ceremony Wednesday.“He was just a dynamic individual,” longtime friend and retired firefighter Dan Prince, 77, told The Post.

“That was him.”Delendick, who joined the FDNY as a chaplain in May 1996, also officiated weddings and baptisms — and gave spiritual support at all hours, according to friends and co-workers.“He couldn’t do enough for the people.He never was off duty,” Prince said.

On Sept.11, 2001, Delendick rushed to the World Trade Center offer firefighters spiritual support as they suffered through injury, chaos and the deaths of co-workers after the terrorist attack.In the years that followed, he officiated countless funerals of firefighters who died of 9/11-related illnesses after inhaling toxic chemicals at ground zero.He was later himself diagnosed with pancreatic cancer linked to the rescue effort, FDNY officials said.“I don’t think it changed him, other than it slowed him down.

He didn’t give up,” Prince said.On Wednesday, thousands of FDNY workers gathered at  Riverside Park in Manhattan to honor Delendick and 13 other members of the bravest who died in the past year.Of the FDNY workers who lost their lives last year,  two died in the line of duty, both from cardiac arrest,...
