Fun fact: A seashell is sometimes used to scoop and pour water over the baptized head. It has been a symbol of baptism since the 12th century. Not only did it prove to be a practical tool to pour water on someone, it was also used as the symbol of a pilgrimage.
š§³ Since Baptism is the start of the Christian journey, a priest sometimes uses a shell to pour the water. The priest is initiating the baptized on a pilgrimage toward heaven!
š¦ The seashell is often pictured with three drops of water, which represent the Trinity.
