Blue Book #99 m-o, 100 g,h
Each one must consecrate himself to my Immaculate Heart, and through you priests many of my children will make this consecration.
This is like a vaccine which, like a good Mother, I give you to preserve you from the epidemic of atheism, which is contaminating so many of my children and leading them to the death of the spirit.
These are the times that I myself foretold; this is the hour of the purification. Heed the requests of your Mother, and entrust yourselves to me with all confidence and the most complete surrender.
Do not be surprised if, in this battle, those fall who did not want or did not know how to use the weapon that I myself gave you: my prayer, the simple and humble prayer of the holy rosary.
It is a simple and humble prayer, and therefore it is most efficacious in combating Satan who today is leading you astray especially by ostentation and pride.
Entering deeply into the mysteries of the beads is entering into the whole immense mystery of the life and death of our Lord Jesus Christ. And who better to guide us than Mary? She was there at the beginning, during his public life, death, resurrection, and afterward in the upper room when the Spirit descended. She “started it all” in a manner of speaking with her yes. So we ask her to lead us through the mysteries of her Son with devotion and faith.
Grace in Every Season (May 6)
The following is taken from the MMP site.
Why does Our Lady urge the formation of cenacles?
In her messages, Our Lady insistently calls upon priests, religious and faithful to gather together with her in fervent prayer and fraternal love, in authentic cenacles as when the first apostles gathered with her in the Upper Room in Jerusalem awaiting the outpouring of the Holy Spirit. Why this insistence? What is most important in the world and in the Church today is the preparation for the Second Pentecost through the triumph of her Immaculate Heart. To draw down upon us this gift of the Holy Spirit, we must enter with her into the cenacle.
Our Lady invites us to enter into the cenacle of her Immaculate Heart by means of our consecration. In the cenacle of her Heart she will nourish, form, and help us to grow in perfect consecration to her. She calls us to form cenacles together with her and to multiply and spread them everywhere, so that the Divine Spirit of Love may pass through the golden door of her Immaculate Heart and thus prepare humanity for a new era of grace and holiness.
(cf. 226j, June 7, 1981)
“Just as in the Cenacle of Jerusalem the Apostles, reunited with me in prayer, prepared for the moment of the first Pentecost, so also, in the cenacle of my Immaculate Heart – and consequently in the cenacles where you are gathered in prayer – you apostles of these last times can, with your heavenly Mother, obtain a new effusion of the Holy Spirit.”
