A man who worked for Billy Graham for four years is claiming that the famous evangelist did not write two statements recently issued under his name. Writing on the Huffington Post Religion blog, Steve Knight says that a recent fundraising letter that quotes Billy’s wife saying “If God doesn’t punish America, he’ll have to apologise to Sodom and Gomorrah,” and a statement in which Billy came out behind the campaign to support Chick-fil-A and said he planned to visit a restaurant on Chick-fil-A appreciation day (later amended to say he would eat chicken at home) do not sound like the authentic voice of Billy Graham. “Mr Graham never made political statements like this in the 62-year history of the ministry,” Knight writes. He says that Graham, 93, is suffering from advanced stage of Parkinson’s disease (as well as other ailments) and has been having fluid drained from his brain on a regular basis over the past decade. Chick-fil-A has become controversial in the US after the owner came out in support of traditional marriage and there were calls to ban the firm from Chicago, Boston and New York. Chick-fil-A appreciation day was called by Mike Huckabee and led to record sales. Knight suggests that Billy Graham’s son, Franklin, is now setting the agenda for the Billy Graham Evangelistic Association.
