Ardent supporters saw the photo op as a blow against evil while others saw the gesture as cynical and a ployOn Monday when Donald Trump raised overhead a Bible – the Sword of the Spirit, to believers – he unwittingly cleaved his loyal Christian supporters into two camps. His most ardent evangelical supporters saw it as a blow against evil and described his walk from the White House to St John’s Episcopal church, over ground violently cleared of protesters, as a “Jericho walk”.The Rev Johnnie Moore, president of the Congress of Christian Leaders, described Trump in shepherd-like terms on Twitter:“I will never forget seeing @POTUS @realDonaldTrump slowly & in-total-command walk from the @WhiteHouse across Lafayette Square to St. John’s Church defying those who aim to derail our national healing by spreading fear, hate & anarchy. After just saying, ‘I will keep you safe.’”But evangelicals are not monolithic: some saw the gesture as cynical, a ploy by a president whose decisions, both private and public, do not align with biblical principles.“I guess it’s a sort of Rorschach test, then,” said Dallas pastor Robert Jeffress, who is one of Trump’s most important defenders among the faithful. “You see what you expect to see.”But that’s not true, Trump’s emerging evangelical critics say: an objective measure is contained in the very book Trump wielded.“Blessed are the peacemakers! Blessed are the merciful! It’s right there in the Sermon on the Mount,” said John Fea, a professor of American history at Messiah College. “Just read Jesus.”Trump’s photo opportunity required police to attack and push away protesters against police brutality. He walked surrounded by key civilian and military advisers, some of whom later said they were caught unaware by the stunt and the violence that preceded it. Some evangelical leaders said they felt similarly aghast, watching the event unfold.“Pelting people with rubber bullets and spraying them with teargas for peacefully protesting is morally wrong,” said Russell Moore, president of the Ethics & Religious Liberty Commission of the Southern Baptist Convention. “What we need right now is moral leadership – from all of us, in the churches, in the police departments, in the courts, and in the White House. The Bible tells us so. So do our own consciences.”The day’s events left Moore “alarmed”, he said.The staunchest of evangelicals, 90-year-old televangelist Pat Robertson, split from Trump on Tuesday.He told his television viewers of the president: “He said, ‘I’m ready to send in military troops if the nation’s governors don’t act to quell the violence that has rocked American cities.’ A matter of fact, he spoke of them as being jerks. You just don’t do that, Mr President. It isn’t cool!”It could be far worse than uncool, politically.Trump can’t afford to lose evangelicals, even by the handful. A record 81% of white evangelicals voted for him in 2016, and he only narrowly won the presidency, sometimes by just a few thousand votes in crucial areas. His gesture with the Bible outside St John’s was meant to shore up that support, reminding his base of a tacit agreement. “It’s a contract between him and evangelical voters,” Fea, the professor, who is a Christian, said. In exchange for their ballots, he said, Trump has packed the courts, including the supreme court, with conservative judges who agree with them on social issues. So while evangelicals lifted Trump to power by voting together, they may prove his undoing if a contingent breaks away. In which case his campaign might shudder to hear of evangelical believers like Anthony Kidd in Daphne, Alabama.During the week Kidd works at a salvage yard, and on weekends he does audio work during church services. He’s conservative. “The past few years he has done things that are good for Christians, I’ll grant that,” he said. But when he saw Trump lift the Bible outside St John’s, he said, “It made me want to throw up a little bit.”Fea said it was unclear what happens next: whether evangelicals will stay by Trump, or make a significant split. But whatever happens, he said, is unlikely to be peaceful.“Here’s a good rule of thumb,” he said. “Looking back through history, whenever you see someone in authority using the Bible to justify law and order, it ends badly.”
