Messianism. The sin of believing that a merely human person or system can usher in the eschaton. This is often tipped off by phrases like: “The most important election of our lifetime” (which one wasn’t?); or “God’s man for the hour.”
Selective Scripturization. The sin of using Scripture to reinforce whatever attitude toward the president you feel like holding, while shellacking it with a thin spiritual veneer. If the candidate you like holds office, you consistently point people toward Romans 13: “Everyone must submit himself to the governing authorities, for there is no authority except that which God has established.” If your candidate lost, you consistently point people to Acts 4:10 where Peter and John say to the Sanhedrin: “Judge for yourselves whether it is right in God’s sight to obey you rather than God.” It’s just lucky for us the Bible is such a big book.
Easy Believism. This is the sin of believing the worst about a candidate you disagree with, because when you want them to lose you actually want to believe bad things about them. “Love is patient, love is kind,” Paul said. “Love does not delight in evil, but rejoices in the truth.” But in Paul’s day nobody ran for Caesar. There was no talk radio.
Episodism. The sin of being engaged in civic life only on a random basis. The real issues never go away, but we’re tempted to give them our attention only when the news about them is controversial, or simplistic, or emotionally charged. Sustained attention to vital but unsexy issues is not our strong suit.
Alarmism. A friend of mine used to work for an organization that claimed both Christian identity and a particular political orientation. They actually liked it when a president was elected of the opposite persuasion, because it meant they could raise a lot more money. It is in their financial interests to convince their constituents that the president is less sane than Jack Nicholson in The Shining. Alarmists on both sides of the spectrum make it sound like we’re electing a Bogeyman-in-Chief every four years. I sometimes think we should move the election up a few days to October 31.
One Issue-ism. Justifying our intolerance of complexity and nuance by collapsing a decision into a simplistic and superficial framework.
Pride. I couldn’t think of a snappy title for this one. But politics, after all, is largely about power. And power goes to the core of our issues of control and narcissism and need to be right and tendency to divide the human race into "us" vs. "them."
