Every morning when a Dominican dons the habit, he or she is reminded of the fact that he or she is in the middle of a war. The habit hasn’t changed much since it was given to Saint Dominic and the first friars and nuns of the Order of Preachers – white tunic and scapular with a belt, black cappa (and veil for the sisters). But conspicuously attached to the belt where a medieval knight would have slung a sword, is a rosary.
