Just-In-Case Christian 

What people who don't think they need to be forgiven for anything call people who think they'll be forgiven for everything. Normally it's fun to point out hypocrisy, but when the person doing so is being a hypocrite in the process, it threatens to break the Logical Shitstorm Continuum.

"Godless people like to point out all the just-in-case Christians, yet they're no better since they don't think they require forgiveness for anything. Must be nice to always have a clear conscience because you're your own god."
