Mississippi Governor Phil Bryant signed a gun rights bill on Friday allowing churches to create security programs designating members to carry firearms to defend worshipers against violence.
The legislation, called the "Mississippi Church Protection Act," also makes it easier for residents in other settings to carry concealed weapons, drawing criticism from national gun control advocates.
It was passed amid heightened concerns about church security after a gunman last June killed nine black worshippers during a Bible study session at a church in Charleston, South Carolina, an attack that authorities say was racially motivated.
"Churches deserve protection from those who would harm worshippers," said Bryant, a Republican, in a Twitter post explaining his decision to sign the measure into law.
In most states, churches could address security concerns with similar programs without the need for a new law, according to Amy Hunter, a spokeswoman for the National Rifle Association gun rights lobbying group which supported the measure providing civil liability immunity.
The legislation also allows Mississippi residents eligible to own a gun to carry a firearm in holsters without a permit, she said, expanding on a state law enacted last year allowing for similar access in purses, bags and briefcases.
However, gun control proponents called the law dangerous.
"Mississippi law enforcement, families and faith leaders all spoke out against this reckless bill that will allow dangerous people to carry hidden, loaded handguns in public without a permit," said Shirley Hopkins Davis, a volunteer with the Mississippi chapter of Moms Demand Action for Gun Sense in America, in a statement.
Participants carrying firearms for church security programs must have safety training and meet permitting standards.
