You may have read this morning of Colin Atkinson's coming disciplinary hearing for displaying a crucifix on the dashboard of his company van. You may also have contrasted this with the Muslim Council of Britain proclaiming that all Moslem women should cover their faces and no their views on the matter weren't required thank-you very much. Colin's on a hiding to nothing, I think; you see, it's a company vehicle. He should no more decorate it with crucifixes than with American flags. But I think pious Christians are missing a trick here.
If you want to proclaim your Christian faith, why not adopt the clerical collar? There's no restriction on it, unless you intend to impersonate a clergyman with criminal intent. The gear is widely available over the internet at reasonable prices in a variety of colours. You can even choose between the traditional RC 'peephole' collar and the old CofE 'dog' collar, in plastic or acetate, with or without studs, or even worn on a bib under a waistcoat. And of course it bears no religious sign or symbol at all. The ordained clergy can adopt some supplementary minor mark of distinction, perhaps adding a Biretta to their public dress.
Of course there may be minor drawbacks. Drunks will touch you for money, and the maudlin will attempt to confess their sins to you. You will also feel obliged to become a better, more moral person whilst simultaneously becoming a babe magnet. But the thought of thousands of van drivers, shop workers, quantity surveyors and other ordinary pious peoples all sporting this visible mark of their faith outweighs all disadvantages. The clerical collar as street wear is an idea whose day has come.
