Ten years after the manifestation of the Miraculous Medal to Sister Catherine Laboure in 1830, the Blessed Mother entrusted the Green Scapular of the Immaculate Heart to Sister Justine Bisqueyburu, likewise a Daughter of Charity of St. Vincent de Paul.The manner of using the Scapular was indicated by the Blessed Virgin. Since it is not the badge of a confraternity but simply a double image attached to a single piece of cloth and suspended from a cord, investiture is not required. It suffices that it be blessed by a priest and worn by the one for whom it is intended. Or place in a room.
