Is Christianity being marginalised?

While stories of marginalised Christians continue to make headlines, Jonathan Bartley suggests the m

Hardly a month seems to go by these days without a high profile story in the newspapers concerning another Christian who is feeling discriminated against or claims by church leaders that Christianity is being ‘marginalised.'

In December it was local authorities re-branding the Christmas season ‘Winterval,' schools failing to stage traditional nativity plays, as well as conspiratorial tales about the Post Office issuing a secret memo (of which no one yet seems to have found a copy) telling its workers not to sell religiously themed stamps. One MP even raised the spectre of ‘Christianophobia’ in a debate in the House of Commons.

I was asked to come on Radio 4’s Sunday Programme to discuss the idea with Mark Pritchard, the Tory in question, and dispute his claims. However I was subsequently called by the producer to say that the MP had refused to debate with me. Apparently Pritchard doesn’t believe that Christians should be seen to disagree publicly. (Treating me less favourably because of my faith, I suggested mischievously!)

But the MP was quite prepared to publicly criticise the Archbishop of Canterbury over his recent Sharia comments - so it seems there must have been another reason. One possibility is that the claims being made simply don’t stand up to serious scrutiny.

It is not well known, but it is often the same group of people who fuel the scare stories of Christian marginalisation that appear in the papers. These usual suspects - a small collection of lobby groups -- are actively seeking out potential cases of discrimination which they can then publicise, make a political campaign of, or pursue in the courts. They are also drawing advice and training from the US, where similar strategies have been pursued.

What is behind their zeal? Their agenda is a desperate attempt to win back, or at least try to maintain, many of the special privileges and exemptions that Christianity has previously enjoyed, but which society is no longer willing to grant. Their argument is that since Britain is a Christian country, their faith, and its adherents, should have special recognition and dispensation.

But they are faced with an internal contradiction which virtually guarantees their failure - and helps to explain why their have had so little success. On the one hand they advance their arguments by citing the 70% of the country which identified with Christianity at the last census. This majority position, they argue, means that Christianity should still be given pride of place. However in the next breath, they plead Christians as a vulnerable and persecuted minority in need of special protections - which entirely undermines their case.

Their dilemma will not be resolved anytime soon. But this won’t end the religious conviction that drives them. Indeed, every failure only serves to reinforce their conviction that Christians are being marginalised and sidelined, and that they must fight even harder.

So prepare for a lot more of the same in the months to come – but don’t be afraid to treat the headlines with the scepticism they deserve.

Inside Big Ben: why the world’s most famous clock will soon lose its bong

Every now and then, even the most famous of clocks need a bit of care.

London is soon going to lose one of its most familiar sounds when the world-famous Big Ben falls silent for repairs. The “bonging” chimes that have marked the passing of time for Londoners since 1859 will fall silent for months beginning in 2017 as part of a three-year £29m conservation project.

Of course, “Big Ben” is the nickname of the Great Bell and the bell itself is not in bad shape – even though it does have a huge crack in it.

The bell weighs nearly 14 tonnes and it cracked in 1859 when it was first bonged with a hammer that was way too heavy.

The crack was never repaired. Instead the bell was rotated one eighth of a turn and a lighter (200kg) hammer was installed. The cracked bell has a characteristic sound which we have all grown to love.

Big Ben strikes. UK Parliament.

Instead, it is the Elizabeth Tower (1859) and the clock mechanism (1854), designed by Denison and Airy, that need attention.

Any building or machine needs regular maintenance – we paint our doors and windows when they need it and we repair or replace our cars quite routinely. It is convenient to choose a day when we’re out of the house to paint the doors, or when we don’t need the car to repair the brakes. But a clock just doesn’t stop – especially not a clock as iconic as the Great Clock at the Palace of Westminster.

Repairs to the tower are long overdue. There is corrosion damage to the cast iron roof and to the belfry structure which keeps the bells in place. There is water damage to the masonry and condensation problems will be addressed, too. There are plumbing and electrical works to be done for a lift to be installed in one of the ventilation shafts, toilet facilities and the fitting of low-energy lighting.

Marvel of engineering

The clock mechanism itself is remarkable. In its 162-year history it has only had one major breakdown. In 1976 the speed regulator for the chimes broke and the mechanism sped up to destruction. The resulting damage took months to repair.

The weights that drive the clock are, like the bells and hammers, unimaginably huge. The “drive train” that keeps the pendulum swinging and that turns the hands is driven by a weight of about 100kg. Two other weights that ring the bells are each over a tonne. If any of these weights falls out of control (as in the 1976 incident), they could do a lot of damage.

The pendulum suspension spring is especially critical because it holds up the huge pendulum bob which weighs 321kg. The swinging pendulum releases the “escapement” every two seconds which then turns the hands on the clock’s four faces. If you look very closely, you will see that the minute hand doesn’t move smoothly but it sits still most of the time, only moving on each tick by 1.5cm.

The pendulum swings back and forth 21,600 times a day. That’s nearly 8m times a year, bending the pendulum spring. Like any metal, it has the potential to suffer from fatigue. The pendulum needs to be lifted out of the clock so that the spring can be closely inspected.

The clock derives its remarkable accuracy in part from the temperature compensation which is built into the construction of the pendulum. This was yet another of John Harrison’s genius ideas (you probably know him from longitude fame). He came up with the solution of using metals of differing temperature expansion coefficient so that the pendulum doesn’t change in length as the temperature changes with the seasons.

In the Westminster clock, the pendulum shaft is made of concentric tubes of steel and zinc. A similar construction is described for the clock in Trinity College Cambridge and near perfect temperature compensation can be achieved. But zinc is a ductile metal and the tube deforms with time under the heavy load of the 321kg pendulum bob. This “creeping” will cause the temperature compensation to jam up and become less effective.

So stopping the clock will also be a good opportunity to dismantle the pendulum completely and to check that the zinc tube is sliding freely. This in itself is a few days' work.

What makes it tick

But the truly clever bit of this clock is the escapement. All clocks have one - it’s what makes the clock tick, quite literally. Denison developed his new gravity escapement especially for the Westminster clock. It decouples the driving force of the falling weight from the periodic force that maintains the motion of the pendulum. To this day, the best tower clocks in England use the gravity escapement leading to remarkable accuracy – better even than that of your quartz crystal wrist watch.

In Denison’s gravity escapement, the “tick” is the impact of the “legs” of the escapement colliding with hardened steel seats. Each collision causes microscopic damage which, accumulated over millions of collisions per year, causes wear and tear affecting the accuracy of the clock. It is impossible to inspect the escapement without stopping the clock. Part of the maintenance proposed during this stoppage is a thorough overhaul of the escapement and the other workings of the clock.

The Westminster clock is a remarkable icon for London and for England. For more than 150 years it has reminded us of each hour, tirelessly. That’s what I love about clocks – they seem to carry on without a fuss. But every now and then even the most famous of clocks need a bit of care. After this period of pampering, “Big Ben” ought to be set for another 100 or so years of trouble-free running.
