In the Constitution Ineffabilis Deus of 8 December, 1854, Pius IX pronounced and defined that the Blessed Virgin Mary “in the first instance of her conception, by a singular privilege and grace granted by God, in view of the merits of Jesus Christ, the Saviour of the human race, was preserved exempt from all stain of original sin.”

“The Blessed Virgin Mary . . .” The subject of this immunity from original sin is the person of Mary at the moment of the creation of her soul and its infusion into her body.      Play – Flos Carmeli

In 1830 at the Carmelite Monastery at Warrenmount, Dublin, the Prioress and some of the Sisters had for sometime felt a strong desire for the foundation of a convent in honour of the Immaculate Conception of Our Lady. “We often spoke of it at recreation and Sr. M. Vincent would always say, Our Blessed Lady should find a house for us – and it should be rent free.”

When Archbishop Murray visited Warrenmount on the Feast of Our Lady of Mount Carmel he was told of this desire. The Archbishop said: “I don’t know of any place except that little convent where the Sisters of Charity were.” (It was then vacant) After some days prayer it was decided to accept the offer and the Archbishop was informed of the decision. He visited Warrenmount again and kindly undertook to provide for the house rent and Chaplaincy- as the small sum for the new colony would not have sufficed to defray either. Arrangements were made for the necessary work to be done at the new convent, the expense of which the Archbishop also defrayed.

Later the Prioress wrote to the Archbishop – who was at that time at Clongowes College, to ask his permission for the sisters to take possession of the new convent on the (14 August) Eve of the approaching Festival of the Assumption of our Blessed Lady. In his reply he wrote:

“They have my full permission to commence under the auspices of the Holy Virgin and to adopt all the measures that may be necessary for that purpose … When you spoke of the Immaculate Conception, I did not recollect that the little Altar of North William Street (Convent) was dedicated to God under that Title.”
