I believe that it has long been the case that too many people – particularly those who take a left of centre approach to politics – make the mistake of failing to acknowledge the power of faith in people’s lives? With debate raging about veils, faith schools and social cohesion I wonder if it isn’t time for those who espouse the ‘progressive’ agenda to debate just how to reconcile faith with our modern, pluralistic democracy?

We are not alone in struggling with this issue. In the United States the up and coming Democratic Senator, Barack Obama, has recently argued that his own party has been reluctant to engage in serious debate about the issue of religion and politics. Speaking back in June of this year he said: ‘At best, we [Democrats] may try to avoid the conversation about religious values altogether, fearful of offending anyone and claiming that – regardless of our personal beliefs – constitutional principles tie our hands.’

The reality of political engagement is that we have to meet people where they are – even if we do not agree with where they are. If, as a progressive movement, we are to communicate our hopes and values in a way that’s relevant to the lives of others we cannot abandon the field of religious discourse.

In his speech, Obama argued that secularists are wrong when they ask believers to leave their religion at the door before entering into public debate. Indeed, he makes the case that the majority of great reformers in American history – he cites Lincoln, Dorothy Day and Martin Luther King – were not only motivated by faith, but repeatedly used religious language to argue for their cause.

Democratic engagement makes demands of religious believers. It demands that those who are religiously motivated act to turn their concerns into universal, rather than faith-specific, values. Democratic engagement demands that the values espoused by people of faith be subject to argument and debate.

For example, if I am opposed to abortion on religious grounds and would seek to see the time limit for abortions reduced from 24 to say 20 weeks it is not sufficient to simply invoke the teachings of the Catholic Church to support my views. I will also need to explain why abortion violates some strongly held principle or set of values that are accessible to people of all faiths and none.

Politics, and in particular democratic politics, involves the art of compromise, the art of what’s doable, what’s achievable and what’s possible. For some people of faith this is the greatest challenge that living in a democracy raises. For some people having faith is having certainty, what matters is not what can be done given the circumstances, what matters is not pragmatism but principle. Therefore what is needed is a sense of proportion and a willingness to engage openly and fair-mindedly.

During his campaign to become a US Senator Barack Obama received an email from a doctor at the University of Chicago Medical School that said the following: ‘Congratulations on your overwhelming and inspiring primary win. I was happy to vote for you, and I will tell you that I am seriously considering voting for you in the general election. I write to express my concerns that may, in the end, prevent me from supporting you.

The doctor described himself as a committed Christian who understood his own beliefs to be ‘totalizing’. His faith had led him to a strong opposition to abortion and gay marriage.

But the reason the doctor was considering not voting for Obama was not simply the would be Senator’s position on abortion. Rather, it was because he had read an entry that Obama’s campaign had posted on his website, which suggested that he (Obama) would fight ‘right-wing ideologues who want to take away a woman’s right to choose’. The doctor went on to write: ‘I sense that you have a strong sense of justice … and I also sense that you are a fair minded person with a high regard for reason … Whatever your convictions, if you truly believe that those who oppose abortion are all ideologues driven by perverse desires to inflict suffering on women, then you, in my judgment, are not fair-minded.’

This had a profound effect on Obama. Re-reading the doctor’s letter he felt a pang of shame. He wrote back to the doctor thanked him for his advice and the next day he changed the language on his website to state in clear but simple terms, his pro-choice position.

According to Obama it is people like the doctor who emailed him who are looking for a deeper, fuller conversation about religion and politics. The doctor represents many (possibly a majority) who may not change their positions on issues like abortion, the death penalty or gay rights, but are willing to listen and learn from those who are willing to speak in fair-minded words.

This then is the challenge for those who describe themselves as progressive politicians. They too must become more ‘fair minded’ more willing to engage with people of faith so that they might recognize some overlapping values that both religious and secular people share when it comes to the moral and material direction of modern Britain.
