People who regard Scripture as having passed from God to man without error have warned for years what happens when these texts are treated as something less than accurate. Once compromises are made (and I'm not talking about stoning adulterers, though such a practice might be one way to implement term limits in Washington), all things become not only possible, but probable.
If God is not God and if man says God didn't say what He has said, then what standard is to be used to judge anything? It is more than a slippery slope. It is slippery theology with potential consequences that are eternal. Who gets to decide, God or man? If man, then man becomes God and God is diminished, at least in man's eyes.
