There are certain ways of behaving that we have come to think of as Christian. They are roughly those that are in accordance with the moral teachings of Jesus. People may, for example, use the expression "That's not very Christian of you" when somebody behaves outside those expectations of Christian behavior.
My observation, admittedly informal, is that the behavior of atheists is noticeable more Christian than the behavior of many Christians. And I think that is what jar was commenting on.
