The Fleur-de-lis (French for “Flower of the Lily”) has had many Christian meanings. This image was adopted as a royal symbol by the kings of France, and thus it symbolizes royalty. The lily is also an ancient symbol for purity, and so the Fleur-de-lis represents our most-pure queen, the Blessed Virgin Mary. Finally, the three petals of this single flower symbolize the Holy Trinity: three divine Persons united in one God.
