Immaculate Conception Seminary School of Theology (ICSST) is the
school of theology of Seton Hall University and the major
seminary of the Catholic Archdiocese of Newark. ICSST admits both
seminarians studying for the Catholic priesthood and lay students.
Founded in 1861 at Seton Hall, ICSST remained part of the University
until 1926 when it moved to separate facilities in Darlington, near
Mahwah. In 1984 Immaculate Conception Seminary reaffiliated with the
University.
As a house of formation, the Seminary offers men preparing for
priesthood the personal, academic, ministerial and spiritual formation 
essential for conversion to Jesus Christ and their commitment to a life
of service to the Church.
As a school of theology, the Seminary provides a theological
foundation and a pastoral and spiritual formation for men and women
preparing for ministries among the People of God, and a theological
foundation for men and women desiring to pursue doctoral studies and
varied opportunities for continuing theological education.
