The present paper focuses on Marian issues in the context of the spiritual life of consecrated virgins living in the world. The purpose of the publication is to enrich reflection on the identity of persons consecrated in the Ordo virginum. The work in the field of practical ecclesiology is directed primarily to the consecrated virgins themselves and to the persons engaged in their formation. First, the character of Marian spirituality and devotion is outlined, then the reflection addresses three main problems: Mary as the mother and the motherhood both of the Church and of the consecrated virgin; Mary as the sister and the mystery of the ecclesial communion; Mary as the teacher and the type of the Church along with the conditions of acting in persona Ecclesiae for the consecrated woman.
