So I am an Atheist. I need to fire a hardcore Christian freak from my business. I don't like that they're a Christian. How should I fire them without them knowing I am being discriminatory? They're a great employee, but I can't have Christians working for me

The definition of "discriminatory" here would be "a refusal to treat all employees equally, based on certain distinctions between employees."  As a quick aside, it's not common practice to fire an otherwise-good employee.
