Alastair Campbell famously said he didn't do God. The Bishop of Rochester, Dr Michael Nazir-Ali, thinks he should have done. The former Prime Minister himself, in Part Three of The Blair Years to be screened next Sunday, explains that while there is no point pretending he doesn't have a personal faith, he didn't want to come over as a "nutter."
This raises a difficult question for me. As a Christian, I not only approve of politicians who are influenced by Jesus's teaching, I would have difficulty voting for one who wasn't. The main reason I could never bring myself to vote for Neil Kinnock even though he made possibly the greatest speech of the last 30 years was that he was a self-confessed atheist.
But at the same time, I also dislike politicians who claim, or appear to claim, that they have some sort of "hotline" to God that influences not just their general political thinking, but individual political decisions. Mr Blair has clearly implied this in the past in relation to Iraq, for instance.
Whether or not this made him look like a "nutter," it certainly brought Christianity into disrepute by making it appear as if the Christian "viewpoint" on Iraq was pro-war, when in fact the question of whether the Biblical commandment Thou Shalt Not Kill extends to military conflict has always been a hotly-disputed theologically issue.
So I am not entirely sure I agree with Dr Nazir-Ali on this, although it doesn't entirely surprise me to see him criticising Mr Blair. He was, after all, George Carey's chosen successor as Archbishop of Canterbury, but the former Prime Minister went for Dr Rowan Williams instead.
The problem with Tony Blair was not that he was a Christian, nor even that he occasionally made references to the fact, but that he too often allowed himself to sound as if he, alone, had the mind of Christ. The truth is none of us can claim that - at least, not this side of Heaven.
