The stole is a long piece of cloth that is worn around the priest's neck like a scarf and descends down the front of his chest, generally terminating around his waist or knees. Although many priests wear it over the chasuble (the next vestment), it is really worn beneath the chasuble. The word "stole" comes from Latin stola, which means "cloak." It has been used since early Christian times in ceremonies when incense was burned before an image of the deity. It became popular again after 10th-century Europe was struck by a wave of religious enthusiasm called the Reconquista. Priests led processions wearing stoles to protect themselves from the heathen natives who may have attacked them. In 1559, one year after his death, Pope Paul IV created the first official look for a Catholic priest. He ordered that a stole be worn by all priests during church services. Before this time, only bishops were expected to wear stoles, but now anyone can join in if they want to. Today, priests still wear stoles, but they are also expected to wear other sacred garments as well. The stole is usually black, but other colors are allowed. In addition, priests often wear amice under their stoles because of the money laundering laws in some countries. Money hidden in holy objects is considered clean because it has not been directly touched by human hands.
