McCain has warned of the threat from extremism in Islam, not the religion as a whole.
On the road to clinching the Republican party nomination for president, John McCain worked hard for the endorsement of influential Evangelical Christian ministers.
The ministers are helping shore up McCain’s support on the party’s right wing, which has always been sceptical about whether the Arizona senator is a true-blue conservative.
But one of those minister’s beliefs about Islam and Muslims raise disturbing questions.
Rod Parsley, the pastor of a large and profitable Ohio mega-church, calls Islam a false religion. He says Allah is a demon spirit and that Muslims are bent on world conquest.
Parsley endorsed McCain in February, praising him as a “strong, true, consistent conservative”.
Sharing a Cincinnati, Ohio, stage with Parsley, McCain said: “I am very honoured today to have one of the truly great leaders in America, a moral compass, a spiritual guide, Pastor Rod Parsley. Thank you for your leadership and your guidance. I am very grateful you are here.”
He certainly had reason for gratitude – a week later, Parsley’s support helped McCain win the important Ohio primary.
Evangelist
Reverend Parsley, who often holds services in which people are supposedly cured of disease by divine intervention, runs the sprawling World Harvest church near Columbus, Ohio.
World Harvest has a 12,000 member congregation, a bible college, and a television studio, which broadcasts his sermons.
A frequent theme of those homilies is the threat to Christian values posed by gays, liberals and Muslims.
In his book, Silent no More, Parsley says the United States was ordained by God to defeat Islam.
In one chapter, titled The Deception of Allah he writes: “I cannot tell you how important it is that we understand the true nature of Islam, that we see it for what it really is. In fact, I will tell you this: I do not believe our country can truly fulfil its divine purpose until we understand our historical conflict with Islam. I know that this statement sounds extreme, but I do not shrink from its implications. The fact is that America was founded, in part, with the intention of seeing this false religion destroyed, and I believe September 11, 2001, was a generational call to arms that we can no longer ignore.”
