In the course of recent centuries there have been any number of saints, founders and foundresses of religious communities, and apostolic laymen like Frank Duff (1889-1980), founder of the Legion of Mary who have been advocates of Marian consecration. Without hesitation, I would point to St. Louis-Marie Grignion de Montfort (1673-1716), the author of the famous treatise, True Devotion to the Blessed Virgin, and St. Maximilian-Maria Kolbe (1894-1941), the Polish Conventual Franciscan martyr of Auschwitz, as two of the most important and influential proponents of Marian consecration among the canonized saints of modern times.
Without a doubt, however, the greatest proponent of Marian consecration in the final quarter of the twentieth century and up to the moment of his death was our late Holy Father, Pope John Paul II. His coat of arms as Bishop and Pope was a blue shield featuring an off-centered cross with the initial M under it, symbolically representing Mary standing at the foot of the Cross of her Son (cf. Jn. 19:25-27), thus underscoring her unique role in the redemption. In iconographic language the statement couldn’t be missed – even if it was a constant source of chagrin to experts in ecclesiastical heraldry. Beneath the shield were the words Totus Tuus (all yours), an abbreviated form of one of Saint Louis de Montfort’s formulas, Totus tuus ego sum et omnia mea tua sunt [I am all yours (O Mary) and everything I have is yours, cf. True Devotion, #233].
