McCain courted in 2008 what I would call 'fringe' evangelicals, in part because evangelicals were skeptical of his commitment to values voters. McCain's embrace of Palin came after having to scuttle endorsements from John Hagee and Rod Parsley, charismatics who believed in Armageddon and fiercely supported Israel.

Evangelicalism's moral values are now articulated by reality stars like the Duggar family, who Mike Huckabee embraced, and 'Duck Dynasty,' whose patriarch, Phil Robertson, endorsed Cruz. Palin herself, an evangelical darling in 2008, has had two reality TV shows: 'Sarah Palin's Alaska' and 'Sarah Palin's Amazing America.'

Charles Finney, the great 19th-century revivalist and evangelical, would have had a hard time preaching a revival in America today. Finney's brand of evangelical fervour, called the 'new measures,' emphasised saving souls and reviving worship by incorporating elements of personal testimony and music into church services.

These 21st-century 'teavangelicals,' who represent a considerable segment of the Republican party, are vastly different from their 19th-century forebears. Nineteenth-century evangelicals were concerned with societal ills such as temperance, slavery, the rise of industrialisation and suffrage.

There is not one particular moment that can account for the shift from the social issue concerns of 19th-century evangelicals into the state of American evangelicalism today. Some historical moments are telling. The rise of biblical criticism in the 19th century forced evangelicals to make choices about what they believed about the gospel.

Mr. Trump and Mr. Osteen are mirrors of each other. Both enjoy enormous support among evangelicals, yet they lack a command of biblical scripture. Both are among the 1 percent.

Graham promoted a white evangelical respectability that wanted to 'put the brakes' on the civil rights movement, and never really accepted women as equal to men. He may have been the country's greatest evangelist, but he was also an apologist for the racist and sexist beliefs pervasive among white evangelical men in 20th-century America.

Graham functioned as a megaphone for conservative biblical ideas that dovetailed with conservative politics, including family, sexual morality, and adherence to laws. He was not only an evangelist, he was also an enforcer: enforcing conservative white Christian social beliefs and evangelical ethical claims as 'America's Pastor.'

What's sometimes called the 'browning' of the American Catholic church is very much on the minds of many U.S. bishops - and the pope. Unlike evangelicals who have stayed strong in their support of President Trump, the USCCB knows that it cannot afford to lose their Hispanic and African American population because of a weak stance on racism.

I'm evangelical on the subject of some chefs and writers.
