Mary's Missionaries

of Mercy

A Rosary ministry

for men, women, and families.

"from that hour the disciple
took her into his home."
John 19:27

Welcome to MMoM!

With gratitude for your interest, we invite you to discern becoming a missionary of prayer in union with Mary's Missionaries of Mercy (MMoM) Rosary groups in and around the Catholic Diocese of Pittsburgh.  Please browse through our website and learn about our missionary call as well as our prayer intentions for the Church and for our World.  Blessed Pope Pius IX once said, "If I had an army to say the Rosary, I could conquer the world."  Let us fight the increasing spiritual battles we face today by heeding our Mother Mary's call to pray the Holy Rosary and invoke her powerful intercession for the conversion, healing, purification and salvation of all souls and for peace in our world.  Do not be afraid to bring Mary, our Mother, ever deeper into your heart... do not be afraid to bring Mary into your home!

Sign up to be a missionary of prayer as a group member or a group leader by registering your name and

e-mail below.  We'll respond to your registration request within three days.

Our Mission and Intentions

As Mary's Missionaries of Mercy, we enter into the life and the mission of the Church with the Blessed Virgin Mary as our mother, our model, and our intercessor.  With devotion, we received this most Blessed Mother as our own as did St. John when our Lord Jesus spoke to the beloved disciple from His Holy Cross, “Behold your mother” (John 19:27).  Upon receiving Mary as his mother, St. John responded with great love and immediate generosity as we are told “from that hour the disciple took her into his home.” At this time of unrest in our world and brokenness in our Church, the Crucified Lord invites us again to “behold our mother” and to bring her into our homes with an ever increasing generosity and trust in her maternal care and intercessory power. Just as Mary gathered with the disciples in the upper room to pray for the coming of the Holy Spirit at Pentecost, MMoM strives to be a modern-day gathering of missionary disciples with our Mother Mary in the “upper room” of our homes and hearts to pray for the purification and healing of our Church and peace in our world – the building of God’s Kingdom here on earth.


As home-based Rosary groups, MMoM responds to our Blessed Mother’s request to pray the Rosary and to pray gathered together as her children on a regular, scheduled basis in our homes. The simple model for MMoM consists of leaders willing to open their homes for a weekly, bi-weekly, or monthly Rosary prayer group committed to pray for the intentions listed below.  Leaders are asked to register their groups through this website (see "contact us" below) before or after inviting a group of individuals to pray in their home.  Other leadership duties include naming the group under the patronage of one of the titles of our Blessed Mother, notifying the group members of scheduled events/changes through e-mail/phone messages, and facilitating the 30 to 40-minute prayer meeting. All MMoM Rosary groups are asked to pray the Scriptural Rosary (available through MMoM) and to use the meditations provided on this website.

Our spiritual adviser, Fr. Adam Potter, is committed to meet with all MMoM groups three times a year for a unified gathering at a central location for Holy Mass, the Rosary, and a reflection on our Blessed Mother and the mysteries of the Rosary. Gatherings events are announced below.  



1. For the intentions of Mary’s Immaculate Heart
