Alistair Campbell, former British prime minister Tony Blair's communications director, once pronounced: "We don't do God". Interestingly today, the Tony Blair Faith Foundation sets out to endorse religion as a force for good in the world.
Interpretations of God vary from religion to religion, and person to person. In an age of growing distrust of our politicians, it might be sensible for them to factor out God from their political judgments. This is not to say they should disregard the needs of religious groups or to remove their moral compasses entirely. But, if they do not want to offend or alienate more people in society, they should choose their words with care.
