A judge has ruled that a Bible-based prison program violates the First Amendment's freedom of religion clause by using state funds to promote Christianity to inmates.

Prison Fellowship Ministries, which was sued in 2003 by an advocacy group, was ordered Friday to cease its program at the Newton Correctional Facility and repay the state $1.53 million.

"This calls into question the funding for so many programs," said Barry Lynn, executive director of the Washington-based Americans United for Separation of Church and State, which filed the suit. "Anyone who doesn't stop it is putting a giant 'sue me' sign on top of their building."

Lynn's group accused Prison Fellowship Ministries of giving preferential treatment to inmates participating in the program. They were given special visitation rights, movie-watching privileges, access to computers and access to classes needed for early parole.

U.S. District Judge Robert Pratt called the perks "seemingly minor benefits" that constituted unfair treatment to those not in the religious program. Despite any claims of rehabilitating inmates, the program "impermissibly endorses religion," Pratt wrote.

The InnerChange Freedom Initiative was implemented in Newton in 1999. State prison officials have said they hired the religious group to improve inmate behavior and reduce recidivism — not promote Christianity.

Ministry president Mark Earley said in a statement Friday that the group plans to appeal the ruling and believes its program is constitutional.

"This decision, if allowed to stand, will enshrine religious discrimination," Earley said. "It has attacked the right of people of faith to operate on a level playing field in the public arena and to provide services to those who volunteered to receive them."

The judge gave the group's workers 60 days to leave the prison, though he put a stay on his order, meaning the decision won't officially be implemented until the appeals process is complete.
