When Jesus spoke again to the people, he said, "I am the light of the world. Whoever follows me will never walk in darkness, but will have the light of life."

The Marine Corps is reconsidering its contract with a Michigan company that has engraved hundreds of thousands of rifle sights with Bible inscriptions, a spokeswoman said Tuesday.

"We are aware of the issue and are concerned with how this may be perceived," USMC spokeswoman Capt. Geraldine Carey told  ABC News. "We will meet with the vendor to discuss future sight procurements."

Trijicon, based in Wixom, Mich., has been making the rifle scopes for the Marines since 2005 -  and carving references to Bible passages next to the scope's serial number.

U.S. military rules prohibit any service member from proselytizing while serving in Iraq or Afghanistan, which are primarily Muslim nations.

But one top U.S. military official defended the inscriptions, saying it doesn't violate any rules.

"The perfect parallel that I see is between the statement that's on the back of our dollar bills, which is 'In God We Trust,' and we haven't moved away from that," said  Maj. John Redfield, spokesman for the U.S. Central Command.

"Unless the equipment that's being used that has these inscriptions proved to be less than effective for soldiers, sailors, airmen, Marines and military folks using it, I wouldn't see why we would stop using that," he said.

Mikey Weinstein, founder of the Military Religious Freedom Foundation, said the sights endanger troops.

"This plays right into the hands of maniacs who say, 'Look, it's a jihad,'"" he said, adding that he's received several complaints from soldiers and Marines.

Weinstein is calling for a Congressional hearing to review the contracts.
