Christian symbolism invests objects or actions with an inner meaning expressing Christian ideas. Christianity has borrowed from the common stock of significant symbols known to most periods and to all regions of the world. Religious symbolism is effective when it appeals to both the intellect and the emotions. The choice of suitable acts and objects for symbolism is narrow enough that it would not be easy to avoid the appearance of an imitation of other traditions, even if there had been a deliberate attempt to invent an entirely new ritual.
