If you've ever campaigned for political change you've probably had someone tell you to “live in the real world”. But witnessing to the truth that Jesus taught involves acting in accordance with the realities our society denies.
Christian groups who fear discrimination say they want a "level playing-field" for British Christians. But if we are to take this concept seriously, let's not only support religious liberty for all people but also give up the privileges that are granted to Christians and denied to others. This would be a powerful demonstration of Christian love in action.
When Christians explore nonviolence, we do so with the legacy of Christian collusion with militarism hanging over us. Nowhere is this more apparent than in the confusion around Christian attitudes to the armed forces.
Disputes over truth are often presented as examples of a clash between religion and science. Galileo's conflict with the Roman Catholic Church is frequently talked about in this way, as are more recent controversies about evolution and creationionism. But an exploration of the details reveals that conflicts over truth are often closely tied to questions of politics and power.
Listening to certain Christians, you would think that opposition to homosexuality is one of the most basic principles of the Christian faith. But this year, as a small group of Christians turn up to protest against the Pride festival in central London, they will be easily outnumbered by the Christians who are participating in Pride, celebrating diverse sexuality as a gift from God.
David Cameron has tried to use Armed Forces Day to whip up support for the unpopular war in Afghanistan, but the ruinous cost of ineffective military spending is clearly at odds with his government's rhetoric about the urgent need for cuts.
When religion is invoked as a reason to stand up against injustice, a cynic might say that religion really has nothing to do with it, that the people involved would have taken the same political action anyway. So does religion really have the power to be an effective force for social change? A brief look at mysticism can help us to answer this question.
Some Christians throw around the word "sin" fairly unthinkingly, while others have become rather embarrassed by it. To talk about "sin" clearly and justly, we need to address the confusion of both society and churches around two major issues - sex and violence.
For the first time in a British general election, significant numbers of voters will today have the opportunity to support candidates from parties described specifically as “Christian”. Symon Hill hopes that very few of them will choose to do so.
The role of religion in the general election is far from straightforward. Politicians and the media need to recognise the diversity of religious engagement with politics on a much wider range of issues than they sometimes seem to notice.
