St. Maximilian may be the greatest promoter of The Miraculous Medal. It became the banner of the MI, and he called it a "spiritual bullet". There is much more to St. Maximilian than many people know. For example, I would guess that most people do not know that one of the main inspirations of his work and "mission" was the profound insight that we are living in the "last days". The Mother of God has come in apparitions to make us aware of this. To prepare to receive Christ The King we are invited, as a preparation, to consecrate ourselves to The Immaculate and to accept her as our Mother and Queen. Here is a page with more information.
