A Pennsylvania church is asking couples to bring in their AR-15 rifles to a mass “blessing ceremony” — a week after a suspected teen gunman used the same weapon to slaughter 17 people at a Florida high school.

The World Peace and Unification Sanctuary in Newfoundland — an offshoot of the controversial “Moonie” church, known for its mass weddings — says the Feb. 28 event is expected to draw 600 couples toting semiautomatic weapons to represent the biblical “rod of iron.”

“This will be a big thing for us. It’s a new stage for us because it incorporates the rod of iron, as it is in Revelations. Revelations talks about the returning Christ ruling with the rod of iron,” church rep Tim Elder told local ABC affiliate Newswatch 16.

Couples who can’t purchase an appropriate gun in time can buy “a $700 gift certificate from a gun store, as evidence of their intent to purchase a ‘rod of iron’ in the future,” the church’s website states.

The church says the event was planned before last week’s massacre, and there’s no connection anyway “since we have no ill intent and since these firearms are for self-defense.”

“Regarding the school shootings, if any of the teachers had been allowed to carry a firearm, many lives could have been saved. Several states have passed legislation to allow exactly that,” president Richard Panzer told the Scranton Times-Tribune.

The guns will all be inspected to make sure they are unloaded and secured with zip ties, he added.

But parents at an elementary school down the road from the house of worship said they still don’t think it’s safe.

“It’s something I would consider keeping my child home. It’s scary,” Liz Zoccola told Newswatch 16.

The Moon family owns a local gunmaker called Kahr Arms.
