Wayne Grudem is a fanatic Biblical inerrantist and evangelical theologian – he has suggested that being non-Christian (by his narrow definition of Christianity) is immoral – most famous for his advocacy of letting the Bible control absolutely every single aspect of life, including those not covered in the Bible, and for being the founder of the Council on Biblical Manhood and Womanhood (CBMW) (current president is Mississippi pastor J. Ligon Duncan, III). Yeah, you get the idea. They advocate complementarianism. Focus on the Family is heavily inspired by their work. Grudem is also the editor (with John Piper) of Recovering Biblical Manhood and Womanhood (which was named “Book of the Year” by Christianity Today in 1992) and the author of Evangelical Feminism and Biblical Truth: an Analysis of over 100 Disputed Questions. You can probably guess your way to his and the CBMW’s position on gay marriage (complete with made-up statistics).
As a Biblical inerrantist it is hardly surprising that Grudem is a creationist – though he suspends judgment on whether he’ll plump for the old-earth or the young-earth variety. To his credit (or whatever you call it) he doesn’t even really bother to try to engage with the science when it comes to scientific questions. Grudem does Bible. Science, truth, evidence or reality aren’t even on his radar.
In 2016 Grudem was one of several fundamentalist recruited to serve on Marco Rubio’s Religious Liberty Advisory Board, which promoted religion very much indeed but had little time for promoting liberty in any recognizable sense of the word.
Diagnosis: This is what the Taliban was made of. Really. Grudem’s views on political and social issues are indistinguishable but for the names. He is also very influential and thus extremely dangerous.
