My former Legion of Mary Praesidium begins a progamme of preparation for the Act of Total Consecration to Our Lady today, as devised by St Louis-Marie de Montfort (whose feast it would be today if it were not Easter Thursday. The ceremony of consecration will take place in St Mary's Church, Drogheda, on the 31st May next.
St Louis-Marie's famous book Treatise on True Devotion to Mary is a spiritual and theological classic, well worth a read. It transformed the lives of Pope John Paul II and Frank Duff, founder of the Legion of Mary. I often wonder how long we have to wait for St Louis-Marie to be declared a Doctor of the Church - I always thought Pope John Paul would have done it. His theology and teaching has had an enormous influence in the Church, one of the criteria for proclaiming a Doctor.
That said, if you want a good spiritual exercise, then this Consecration is as good as you will get. And if you are around Drogheda on the 31st May, you might come to the ceremony.
