Answer:
Their sacred contents brought pilgrims to Christian churches
Explanation:
A reliquary is a religious object; it can be anything, from a piece of cloth to the actual bones of any given saint. In the christian (but also the buddhists) tradition the relics are important because they attract pilgrims from all over the world. A good example is the Pilgrim way to Santiago de Compostela, although the religious or spiritual aspect of this modern pilgrimage has been replaced by tourism.
