‘Praised be You, my Lord, through Sister Moon and the stars’

Lunar references from Scripture, the Catechism, prayers, and Catholic moon trivia

The moon is an analogy for the Church

“The Church has no other light than Christ’s; according to a favorite image of the Church Fathers, the Church is like the moon, all its light reflected from the sun” (Catechism of the Catholic Church, 748)

St. John Paul II wrote about the mysterium lunae (the mystery of the moon), whereby the Fathers of the Church “employed this image to show the Church’s dependence on Christ, the Sun whose light she reflects. It was a way of expressing what Christ himself said when he called himself the ‘light of the world’ (John 8:12) and asked his disciples to be ‘the light of the world’ (Matthew 5:14)” (Novo Millennio Ineunte, “At the Beginning of the New Millennium,” 54).

Mary and the moon

The Blessed Virgin Mary’s life is often characterized as a moon that reflects the light of her son, Jesus. 

St. Bonaventure, the great Franciscan theologian, taught, “The moon transmits light from the sun to the earth. So Mary gives us the heavenly graces which she receives from the Sun of Justice.” 

In the last century, Ven. Fulton J. Sheen wrote about Mary in his book The World’s First Love: 

God who made the sun, also made the moon. The moon does not take away from the brilliance of the sun. All its light is reflected from the sun. The Blessed Mother reflects her Divine Son; without Him, she is nothing. With Him, she is the Mother of men.

Canticle of Brother Sun and Sister Moon

St. Francis of Assisi composed the well-known prayer Canticle of Brother Sun and Sister Moon. Here’s an excerpt: 

Most High, all-powerful, all-good Lord, All praise is Yours, all glory, all honor and all blessings. 

To you alone, Most High, do they belong, and no mortal lips are worthy to pronounce Your Name.

Praised be You my Lord with all Your creatures, especially Sir Brother Sun,

Who is the day through whom You give us light.

And he is beautiful and radiant with great splendor,

Of You Most High, he bears the likeness.

Praised be You, my Lord, through Sister Moon and the stars,

In the heavens you have made them bright, precious and fair.

What is man that you are mindful of him,

and a son of man that you care for him?
