The phrase "Immaculati Cordis Beatae Mariae Virginis" is Latin for "Immaculate Heart of the Blessed Virgin Mary". This is a Catholic devotion which refers to the interior life of Mary, her joys and sorrows, her virtues and hidden perfections, and above all, her virginal love for God the Father, her maternal love for her son Jesus Christ, and her motherly and compassionate love for all mankind.
Interestingly, this phrase is also associated with the **Claretians**, officially named the Congregation of Missionary Sons of the Immaculate Heart of the Blessed Virgin Mary (Latin: Congregatio Missionariorum Filiorum Immaculati Cordis Beatae Mariae Virginis; abbreviated CMF).
The Claretians is a Catholic clerical religious congregation of Pontifical Right for men headquartered in Rome. They were founded on July 16, 1849, by Fr. Antonio María Claret y Clará, C.M.F. They are active as missionaries worldwide, in 70 countries on five continents. The Congregation has a particular devotion to the Immaculate Heart of Mary.
There is a specific feast day for the devotion to the Immaculate Heart of the Blessed Virgin Mary. The feast of the Immaculate Heart of Mary is celebrated on the **Saturday following the Second Sunday after Pentecost**. However, it was originally instituted to be celebrated annually on **August 22** by Pope Pius XII in 1944. Later, in 1969, Pope Paul VI moved the celebration to its current date. Please note that the dates may vary depending on the liturgical calendar.
