What is the history of Pope St John XXIII National Seminary?

Pope St. John XXIII National Seminary was founded in 1964 in Weston, Massachusetts, to prepare men entering Roman Catholic priestly formation later in life. Its founder, Cardinal Richard Cushing, was then archbishop of Boston. That purpose still distinguishes the seminary from institutions organized primarily around applicants entering directly after college.

The institution was formerly known as Blessed John XXIII National Seminary. Its present name reflects the canonization of John XXIII in 2014. Although it is located in the Archdiocese of Boston, its national focus means that men sponsored by other dioceses can undertake formation there.

What are the faculties and departments at Pope St John XXIII National Seminary?

Pope St. John XXIII National Seminary is a specialized graduate seminary, not a university with multiple undergraduate colleges or a broad selection of majors. Its academic work centers on theology and preparation for Catholic priestly ministry, including the Master of Divinity.

Classroom study is one part of priestly formation. Seminarians also undertake supervised pastoral work and participate in spiritual and community formation. Applicants should distinguish the academic degree from ordination: completing a degree does not, by itself, confer eligibility for ordination, which is governed by the Church and the candidate's sponsoring diocese.

What is the location of Pope St John XXIII National Seminary?

The seminary is at 558 South Avenue in Weston, Massachusetts, a suburban community west of Boston. Its setting is residential rather than a downtown college campus, and students should plan transportation around their formation and pastoral assignments.

Weston provides access to the Boston area's churches, educational institutions and transportation network, but regional access should not be confused with an easy walk to every destination. A prospective seminarian assigned to off-campus ministry should ask how travel is arranged and whether a car is needed.

What is the mission and vision of Pope St John XXIII National Seminary?

The seminary's stated purpose is to prepare mature men for Roman Catholic priesthood. Its educational approach joins theological study with human, spiritual and pastoral formation rather than treating a degree as the sole objective.

This is a vocationally specific, religiously affiliated education. Daily worship, prayer, discernment and preparation for diocesan ministry are central to the program. A prospective applicant should therefore consider not only whether he wants to study theology, but whether he is seeking priestly formation with the support of a diocese.
