The Rev. Glenn Germany was preaching to his congregation outside Pittsburgh on Sunday when a man walked up to the pulpit and pointed a handgun at him.

Germany ducked and hid behind a lectern, but not before the man pulled the trigger. It was “a miracle of God,” the pastor later told “Good Morning America,” when the gun jammed and no bullet was fired.

A congregation member, Clarence McCallister, tackled the gunman, identified by police as Bernard Polite, 26. McCallister and Germany struggled with him for the gun; the pastor then held Polite down until police arrived, according to a live-streamed video of the service and the criminal complaint filed against Polite.

Polite was charged with criminal attempt of homicide, aggravated assault and recklessly endangering another person in connection with the attempted shooting. He was jailed in Allegheny County and is represented by a public defender, according to court records.

That evening, police were called to Polite’s North Braddock, Pa., home, where a man had been reported shot. They found Polite’s cousin dead inside the home, authorities said, identified by the Allegheny County Medical Examiner’s Office as Derek Polite, 56.

The medical examiner confirmed that Derek Polite had been shot but said the investigation into his death was ongoing. No charges have been filed in the killing, and police are investigating, said Allegheny County police spokesman Jim Madalinsky.

Polite was unknown to the church, Jesus’ Dwelling Place Church in North Braddock, according to the complaint. He walked in, went back outside and then sat down after Germany began his sermon; after a few minutes, he got up and attempted to shoot, Germany told police.

Polite allegedly told both Germany and a Pennsylvania State Police trooper that God had told him to carry out the shooting, according to the criminal complaint. He allegedly told the trooper that he had planned on shooting Germany, waiting to be arrested and going to jail to “clear his mind.”

“We are surely thankful that the weapon didn’t discharge,” Allegheny County District Attorney Stephen A. Zappala Jr. said in a statement. “This could have been much worse, and a devastating circumstance.”

Germany told “Good Morning America” that he didn’t have time to think when the gunman approached him.

“It was just reaction, you know. Duck and try to get out of the way of his line of fire,” Germany said.

“He pulled the trigger, and a miracle of God happened that the gun got jammed,” he added. He did not immediately respond to a call from The Washington Post on Tuesday.

McCallister told the program, “I just jumped up and … pulled his arm down to his side and locked him up.”

“That was an act of heroism if I’ve ever seen one,” Germany said of McCallister.
