Newt Gingrich is proving that American christianity is a form of neo-victorianism. In that it finds it more distasteful to talk about adultery than it does to committ adultery. This redemption is a form of relativism. "We are all fallen. We all sin." This sickly relativism is American christianity's flexibility...as long as you speak the language of the tribe. If you are outside the tribe you are judged for your sins. If you are within the tribe you are given a pass.
This provinical and tribal theology allows for corrupt double standards and outright hypocrisy.
What is paramount is that one swears fidelity only to the spoken ideology. Your life and integrity is secondary.
