Every year, thousands of pilgrims travel the ancient pilgrimage route to Spain’s Santiago de Compostela. The sacred journey ends with a visit to the shrine that holds the bones of Saint James the Great – Apostle of Jesus. But new research and discoveries suggest that the Camino may have been a sacred pathway long before the Christian age and that the bones in the sacred shrine may not belong to James after all. Instead, they may be the remains of a controversial heretic seen as a threat to the very existence of the Christian church.
