Baptism of Christ
Real or imitation shells are often used in Baptism to help pour the water. Shells have been an emblem of baptism since about the twelfth century. When pilgrimages to the Holy Land became common, shells were often used by pilgrims to help drink water. They became a symbol of pilgrimage. Once pouring water was the accepted mode for baptizing, the shell became a handy accessory and symbolic of our life's pilgrimage.
