(ABC News) -- Walter Slonopas received his W-2 tax form and found the number 666 stamped on it. Calling it a satanic omen, he quit his job.
Slonopas, 52, was a maintenance worker at a metal manufacturing company in Clarksville, Tenn. called Contech Casting LLC.
"I cannot accept this number. If you accept that number, you sell your soul to the devil," Slonopas told ABC News.
According to Robert LaCourciere, the vice president of sales and marketing for Contech Casting's parent company, Revstone Transportation Group, the tax forms are generated by a computer at an outside company. "We are certainly sorry he was put through all this," LaCourciere said. "We hope he does contact us because we'd love to have him back at work."
Slonopas said he feels no animosity towards the company, but doesn't understand the mistake. "My question is, are we working for the computer, or is the computer working for us?"
The 666 number appears in the Bible, in Chapter 13 of the New Testament Book of Revelation. It is sometimes called the Number of the Beast.
Slonopas said it is not the first time he came across the number while working at Contech. On his first day at work in April 2011, the human resources department issued him a work identification card with a ten digit employee number ending the number 666. He said he thought he had been assigned a number ending in 668. He said he brought it to the company's attention and received a card with the correct number.
A few months later, when the company changed its payroll system, he said he received a new ID card with a number ending in 666 again. Slonopas quit, but returned to work a week later after the company apologized.
Slonopas said he became a born-again Christian more than 10 years ago. He said all he wants is a new W-2 form from the company. Otherwise, he said, he wont file his taxes.
Contech said it would accommodate him. "We were able to generate a new W-2 form off the company's system," said LaCourciere. "He should have a new one later today or tomorrow."
Slonopas said, "I don't complain. It just happened because it happened."
