By yielding to the principles of this inner life, the Marian devotion developed in a special way in the bosom of the two fold family of Saint Vincent.

It was consistent with the first sermon of Mr. Depaul and also with the Marian patronage requested by the first Charity, in 1617. It blossomed while remaining faithful to the fundamental rhythm of Vincentian inner life. It undoubtedly benefited from the Marian fervor of the XIX century, but much more even from the apparitions of 1830 to Saint Catherine Laboure.

"The Mother of God was invoked and chosen as Patroness of important things; certainly, everything will lead to a greater good and increase again the glory of good Jesus, her son."
