The devotion is associated with a miraculous apparition in 1467 at Genazzano, Italy, where an image of Mary and the Child Jesus  appeared in an ancient church. This shrine transformed into a site of pilgrimage, with numerous miracles later linked to Mary's intercession there.

Catholics celebrating this feast seek Mary’s assistance in obtaining wise counsel, particularly when faced with challenging decisions, family issues, and spiritual matters. The title “Good Counsel” signifies Mary as a wellspring of wisdom and steadfast guidance.
