The pope said he liked the image so much that he started sending postcards of it, too. Replicas of the image were painted in the pope’s home country, Argentina, and devotion there spread. Once Cardinal Jorge Mario Bergoglio was elected pope in 2013, devotion to Our Lady, Undoer of Knots spread throughout the world.

Francis has talked about the devotion throughout his pontificate, even praying specifically to Our Lady, Undoer of Knots in 2021 during the coronavirus pandemic.

Here is a prayer to Our Lady, Undoer of Knots from Pray More Novenas:

Virgin Mary, Mother of fair love, Mother who never refuses to come to the aid of a child in need, Mother whose hands never cease to serve your beloved children because they are moved by the divine love and immense mercy that exist in your heart, cast your compassionate eyes upon me and see the snarl of knots that exists in my life. You know very well how desperate I am, my pain, and how I am bound by these knots. Mary, Mother to whom God entrusted the undoing of the knots in the lives of his children, I entrust into your hands the ribbon of my life. No one, not even the evil one himself, can take it away from your precious care. In your hands there is no knot that cannot be undone. Powerful Mother, by your grace and intercessory power with Your Son and My Liberator, Jesus, take into your hands today this knot.

[Mention your request here]

I beg you to undo it for the glory of God, once for all. You are my hope.

O my Lady, you are the only consolation God gives me, the fortification of my feeble strength, the enrichment of my destitution, and, with Christ, the freedom from my chains.

Hear my plea.

Keep me, guide me, protect me, O safe refuge!

Mary, Undoer of Knots, pray for me.
