A 40-year-old man attacked a priest during a church service in Spokane, Washington, on Tuesday night, according to officials.

       Around 350 to 400 people had gathered at the Cathedral of Our Lady of Lourdes in downtown Spokane on Tuesday for the second night of novena, a tradition of gathering for prayer for nine days or nine weeks, when the man, identified as Joshua James Sommers, allegedly attacked the priest.

       Security camera footage shows Sommers leaving his pew, rushing up to the altar near the end of the service and attempting to strike Rev. David Gaines in the face. Gaines was able to pin down Sommers, with other staff and churchgoers running up to help.

       In the footage, Sommers lets out screams, and Gaines continues to say, "It's OK, just calm down."

       Security guards quickly came to assist, and the Spokane Police Department was also notified immediately of the incident, according to the church. Gaines was not harmed in the attack.

       Father Darrin Connall, who was kneeling at the altar when the attack occurred, told ABC News the church has not seen "anything quite this serious."

       "All of us were pretty shaken," Connall said. "You don't expect to see something like that when you're gathering together to pray and worship."

       Once Sommers was escorted out by police, Connall said the entire group stopped the service and prayed for him.

       "Whatever demons he was struggling with needed to be healed," Connall said.

       Sommers was arrested on misdemeanor assault charges, and also has a previous record of harming others. In 2023, Sommers was charged with third-degree assault after attacking an employee at a mental health facility. Sommers, who was a patient at this facility, allegedly punched the employee multiple times and stole their keys to try and escape, according to the affidavit on those charges.

       Sommers appeared in court Wednesday on assault charges, along with the outstanding warrant from his previous assault. He will return to court later this month and remains behind bars.
