Toward the back of our venerable 1962 Missale Romanum there are Mass formularies for special feasts. Today, for example, we find Our Lady of the Miraculous Medal.
Our Lady appeared to a Sister of Charity of the Rue du Bac in Paris, St. Catherine Labouré, and showed her the pattern of a medal. Through this medal many miracles have been granted through God by Mary’s intercession.
