Ed Miliband cannot be England's first Jewish or atheist Prime Minister

Mr. Cameron turns out to be a Christian, though, as he self-deprecatingly once said, his faith fades and reappears

“like Magic FM in the Chilterns."

Mr. Clegg also told us this week that he is not an atheist, but an agnostic.  His wife and mother are both devout Catholics, his grandmother a devout Russian Orthodox, so he says that perhaps he will come to believe in God.

An article in the Spectator this week says that Ed Miliband won't be our first Jewish Prime Minister but can be our first atheist Prime Minister. This is inaccurate. Ramsay Macdonald was an atheist and Attlee believed in the Christian 'ethic but not the mumbo jumbo' and therefore was also an atheist. 

Chamberlain was a Unitarian and so not a Christian, but not, I assume, an atheist. (Many Unitarians in our day are atheists, though not in Transylvania, where they are numerous.) 

Most modern Prime Ministers were Christian. Wilson, Callaghan ( a lay preacher), Home, Macmillan, Mrs Thatcher and Mr. Blair were all very religious. Is Gordon Brown? I suspect so, son of the manse that he is. Edward Heath's first job was on the Church Times but I know no more of his religious ideas than this. Churchill was not, though he talked about 'the man upstairs' - he was too much the Edwardian progressive. Bonar Law I think was a freethinker, but my memory might be at fault. Lloyd George liked singing hymns. Salisbury and Balfour were deeply religious Christians. 

Disraeli was a Jew as regards his race but converted to Low Church Anglicanism. Michael Howard, had he become Prime Minister, would have been our first adherent to the Jewish religion to be Prime Minister, as he occasionally enters a liberal synagogue.

I have forgotten whatever I might have known about Asquith and Eden's religious views. Can anyone assist me?
