The controversy with flew is that at the time the book There is a God: How the World's Most Notorious Atheist Changed His Mind, he's mental health was already declining.
Bubblegum Apotheosis wrote It's nice you don't attack Tony Flew has coming down with dementia as other online atheist have charged.
Stating facts are not an attack, and not just online atheists but other well known atheists pointed this out, still this does not meant what he wrote in his book is wrong, we should pass judgment after understanding his points and examin them critically, and not be closed minded.
Here is an interesting citation from My Pilgrimage from Atheism to Theism: an Exclusive Interview with Former British Atheist Professor Antony Flew Gary R. Habermas, Philosophia Christi Vol. 6, No. 2 (Winter 2004) on wikipedia
He supported the idea of an Aristotelian God with "the characteristics of power and also intelligence", stating that the evidence for it was stronger than ever before. He rejects the ideas of an afterlife, of God as the source of good (he explicitly states that God has created "a lot of" evil), and of the resurrection of Jesus as a historical fact though he has allowed a short chapter arguing for Christ's resurrection to be added into his latest book.

Flew was particularly hostile to Islam, and said it is "best described in a Marxian way as the uniting and justifying ideology of Arab imperialism." [5] In a December 2004 interview he said: "I'm thinking of a God very different from the God of the Christian and far and away from the God of Islam , because both are depicted as omnipotent Oriental despots, cosmic Saddam Husseins" . [17]
Sounds like my kinda god lol, with any atheists one question needs to be answered, were is the evidence?
Flew is a philosopher, a dying art since psychology was invented, now lets look back at the controversy.
Book with Varghese
In 2007, Flew published a book titled There is a God, which was listed as having Roy Abraham Varghese as its co-author. Shortly after the book was released, the New York Times published an article by religious historian Mark Oppenheimer, who stated that Varghese had been almost entirely responsible for writing the book, and that Flew was in a serious state of mental decline, having great difficulty remembering key figures, ideas, and events relating to the debate covered in the book. [6] His book praises several philosophers (like Brian Leftow, John Leslie and Paul Davies), but Flew failed to remember their work during Oppenheimer's interview. The article provoked a public outcry, in which atheist PZ Myers called Varghese "a contemptible manipulator." [29]
A further article by Anthony Gottlieb noted a strong difference in style between the passages giving Flew's biography, and those laying out the case for a god, with the latter including Americanisms such as "beverages", "vacation" and "candy". He came to the same conclusion as Oppenheimer, and stated that "Far from strengthening the case for the existence of God, [the book] rather weakens the case for the existence of Antony Flew". [30] Varghese replied with a letter disputing this view. [31] Flew released a statement through his publisher stating that although Varghese did the actual writing, the book belonged to him and represented his thinking. [32] An audio commentary by William Lane Craig [33] concurs with this position, but Richard Carrier disputes this view. [36] In June 2008, Flew stated his position once again, in a letter to a fellow of the Universities and Colleges Christian Fellowship. [7]
Christian writer Regis Nicoll claims that "Moreover, in a signed, handwritten letter (a copy of which I now have) sent to Roy Varghese, the legendary philosopher reaffirmed his conversion while criticising Oppenheimer for drawing attention away from the book’s central argument: the collapse of rationalism." [37] He argues that "Even Mark Oppenheimer described the ex-atheist 'flaunt[ing] his allegiance to deism' in May 2006 to a Christian audience at Biola University."
