Dear Friends,


Welcome to the seminary website!


The Redemptoris Mater Archdiocesan Missionary Seminary is an international house forming priests for the New Evangelization of the Church and for the missio ad gentes. 


The four dimensions of priestly formation, namely human, intellectual, pastoral, and spiritual, are woven together in every candidate preparing to become a priest and a shepherd after the heart of Christ.

The Redemptoris Mater Seminary was opened in September 2005 and officially erected by Cardinal Seán P. O’Malley, OFM Cap, on March 25, 2006.


Encouraged by the example of St. John Paul II, who had opened the first Redemptoris Mater Seminary in Rome in 1987, Cardinal Seán opened the seminary to form priests for the New Evangelization of the Church and for the Missio ad Gentes.

The seminary prepares priests to serve the Church locally and in missionary outposts. It also answers the Second Vatican Council’s concern for the growth of atheism in the world and the need for a better distribution of the clergy. Therefore, priests formed at Redemptoris Mater Seminary receive a special grace from God to go and look for the lost sheep and to re propose the faith to those who have fallen away from the Church. 

Our priests currently serve in the Archdiocese of Boston as pastors and parochial-vicars or have already been sent in mission by the Cardinal.  

Our History
Priestly Formation


Seminarians only.jpg


At Redemptoris Mater Seminary all seminarians are prepared for the priesthood in accord with the four essential pillars of priestly formation, namely human, intellectual, spiritual, and pastoral. 

While the intellectual formation of the seminarians takes place mainly at St. John’s Seminary, in the House the seminarians learn obedience and discipline,

they grow in knowledge of the Scriptures and

come to a deeper appreciation of the Fathers,

the Tradition and the History of the Church.

They also acquire the freedom to become shepherds after the heart of Christ, and to serve the Church

with authority, humility, and prophetic wisdom. 

As part of the international and missionary component of their formation, seminarians are trained to overcome isolation and individualism. Before ordination,

they are also sent in mission for three years during which they discover the grace of God’s Providence as the cornerstone of their future ministry as priests.

Attendance to a local Neocatechumenal community is a distinguishing mark and an essential ingredient of the formation of all seminarians. Together with lay brothers and sisters who are discovering this “special gift which the Holy Spirit has given to our times,” the seminarians grow in the discernment of their vocation and set in place the foundation for the continuous formation to the faith that will accompany them after ordination.
