Father Christopher Heanue had never been stopped, well, dead in his tracks presiding over a funeral Mass. Now, he has — and the timeless occasion is on video, to boot.

Heanue was wrapping up the Feb. 7 service for a beloved 79-year-old grandma when two alleged shoplifters ducked into Holy Child Jesus Church in Queens’ Richmond Hill. Hot on their heels was a good Samaritan who claimed he witnessed the crime.

The deceased and her loved ones were making their way down the main aisle, headed for the doors that the teens ran through, at the time.

Everything came to a screeching halt, except the organ music — and a smartphone recording the action.

The 23-second clip shows the trio standing in the pews, having heated words. There is talk of lighters, presumably what the boys were suspected of taking from the nearby shop.

The man, speaking excitedly in Spanish, has one boy by the sleeve; the other boy — several feet away — tosses a lighter in the direction of his pal.

“Who is this?” a voice off-camera asks, suggesting he means the man.

“He’s chasin’ us for no reason,” one boy answers. “Yeah wow.” Then, the teens dash outside.

Someone called the police about all the commotion — disruption of a funeral is a misdemeanor.

But the cops told Heanue that their hands were tied without knowing the identities of the boys or a complaint from the store owner. They did take a copy of the video with the hope of figuring out who the kids were.

Minutes later, Heanue posted the clip, along with a three-paragraph narrative, to Facebook. He decided the encounter held a teachable moment.

The priest makes his point in his closing: “I do hope these boys return to the church one day under different circumstances. … Not to receive punishment. But to receive God’s forgiveness and perhaps start on a better path for the rest of their days.”
