1. The Evangelical Take on Biblical Inerrancy (e.g., The Chicago Statement)
Any idea or doctrine that must die a death of a thousand qualifications for the sake of plausibility is ... well ... not very plausible. For a better understanding of inerrancy, study Sections 105-107 of the Catechism of the Catholic Church.
2. Penal Substitution Theory of the Atonement
Lying somewhere between a case of divine child abuse and a gross miscarriage of cosmic justice, it’s high time for this monstrous understanding of the atonement to be abandoned. For a more biblical and patristic alternative, read Gustav Aulen’s Christus Victor.
3. Belief in a Young Earth
Face it, the earth’s years are properly measured in the billions, not the thousands. It is time for Christians to admit and accept this fact as a "given," just like other "givens" once disputed by theologians (such as the fact that our spherical earth rotates on its axis while revolving around the sun).
4. Creation Science
Have you checked out any science reviews lately? Creationist polemics notwithstanding, the fossil evidence is actually mounting in favor of biological evolution. But I predict that Genetics, not Archeology, will pound the final nail into the coffin of Creation Pseudo-science.
5. Intelligent Design (related to, but not the same as, above)
What does it say about the state of contemporary evangelical theology that its best argument against Charles Darwin's century-and-a-half old theory rests on a Deistic rehashing of the age-old “god of the gaps” fallacy? For that matter, what does it say about Darwin's theory? Read Ken Miller’s In Search of Darwin’s God.
6. Dispensationalism and the Modern State of Israel
Where does Scripture teach that Israel has an unrestricted, unconditional deed to prime coastal real estate in the Middle East? There is no telling how much political, domestic, and foreign policy damage has been done by Dispensational theology. Remedy: Study the BIBLE, not Scofield's notes, to show thyself approved.
7. The term "Born-Again Christian"
Redundant, misleading, anti-sacramental, ecclesiologically nonsensical, and much too often a blatant oxymoron.
Rather than challenging narcissism, the MegaChurch embraces and institutionalizes it, thus turning narcissism into a Christian virtue. The resulting paradox is a hugely successful message that is profoundly vacuous of any objective content.
9. TULIP Calvinism
Once upon a time there was Isaac Newton, and then came Albert Einstein. Once upon a time there was Theodore Beza, and then came Karl Barth.
10. The “Imminent” Rapture
It’s been 2000 years folks! The end may be a bit closer, but don’t cash in your pension or stop paying your life insurance premiums just yet!
