Welcome to Pope St. John XXIII National Seminary

The Pope St. John XXIII Seminary community is committed to our founding mission: the human, spiritual, academic and pastoral formation of candidates aged 30 and older. Our unique institution is the only American seminary for these mature candidates administered by diocesan priests. For more than five decades, candidates have been accepted from various professional backgrounds; such as law, medicine, business, teaching, sales, banking, social work and military service. The diversity of life experiences shared by these mature seminarians enriches both the Seminary community and their future ministries in the Church.

News and Events

Is God calling you? Have you contemplated the Priesthood and would like to learn more?

On Friday and Saturday - February 10th and 11th - Pope St. John XXIII National Seminary is hosting a Discernment Retreat for men over the age of 30 who are interested in Priesthood. His Eminence, Seán Cardinal O'Malley, OFM Cap., Archbishop of Boston, will be in attendance. Attendees will have the opportunity to live and pray with the Pope St. John XXIII National Seminary community, attend classes and discussion groups, and socialize with seminarians, faculty and staff.

Before the busy Advent and Christmas seasons at Pope St. John XXIII National Seminary, we celebrated an important step in the formation of our seminarians in the Class of 2020.   On December 7th, the Vigil of the Solemnity of the Immaculate Conception, Most Reverend James Massa, Auxiliary Bishop of the Diocese of Brooklyn (also current PSJS XXIII Board member and a former faculty member), instituted these men to serve in a new way in the celebration of Mass.

On Nov. 1, the Solemnity of All Saints, the PSJS XXIII community welcomed to the house Most Rev. Robert C. Evans, Auxiliary Bishop of the Diocese of Providence.  Bishop Evans was with us to institute twelve of our seminarians to the Ministry of Reader.   

This ceremony marks an important step towards ordination. Though they may have been lectors in their own parishes or ministries, now they encounter God's Word in a deeper sense. They proclaim the Scriptures and embrace the role of teachers of God's Word.

Daily Reflection

“One who knows oneself, knows God: and one who knows God is worthy to worship Him as is right. Therefore, my beloveds in the Lord, know yourselves.”
