Anthony Flew's Testimony
For those of you that think the most decided person against the Gospel could ever come to Christ. Flew was an avowed atheist – he wrote on the subject and debated those who believed in God. Thank God that he shames the wise and exalts the foolish.
HT: Primetime Jesus

Flew has become a deist, not a Christian. Even an implication that he may have become a Christian of some sort is to dishonour his integrity and does great disservice to the supposed integrity of Christian apologetics.
Thank you, Noel. You are right. I looked at the article again and realize that I was over zealous. Thanks for the correction.
