The Knights of Lepanto and the Other Marys are specific groups within the MIM for men and women respectively. The life and activity of the Knights of Lepanto and Other Marys is based, in the first place, on the charism of the MIM.

Not all those associated with the Knights of Lepanto or Other Marys formally commit themselves to the organization. Those who wish to do so, must first of all become members of the MIM.
