The Servants of the Lord and of the Virgin of Matarà profess the traditional vows of poverty, chastity, and obedience plus a forth vow of servitude to Mary, according to the spirituality of Saint Louis Marie Grignon de Monfort, the great apostle of the devotion to Mary. The vow to Mary means that the Servants do belong entirely to Mary Queen of the Sky, who will use the servants, by making herself present in their apostolate. The Servants make available all their talents to Mary's saving mission. The result of this practice is to make your life more close to the path of Mary's life.
The ultimate goal of our life is God, and it is easier to reach him by following the path and the prayers of the Virgin Mary. If you want to bring souls to God, you have to spread the devotion to Mary. She has participated fully in the redemption of the world. She is mediator between the grace of God and us. The vow to Mary is a vow to her love to all the human beings and those who profess that love will find fullfilment and joy by Her, who is a Mother.
