The groundwork of the enterprise was laid by J. Francis Stafford, the Archbishop of Denver, now Cardinal, who purchased the site of the former St. Thomas Aquinas Seminary from the Congregation of the Mission in 1995. The facility, which included the Archbishop Vehr Library, had served as the focus for priestly formation for the dioceses and religious orders of the region since 1907. The facility was remodeled and re-named the John Paul II Center for the New Evangelization to serve as a campus for the Archdiocesan Chancery. There was also a vision that the campus would become a resource for priestly formation and the renewal of the Church.
Cardinal Stafford's successor, Archbishop Charles J. Chaput, O.F.M. Cap., advanced this vision by commissioning a study to determine the feasibility of establishing an educational institution on the site. After much consultation with the priests and people of the archdiocese, Archbishop Chaput announced his plan to open a theological institute to serve the formation needs of clergy and laity engaged in the new evangelization.
These plans resulted into what has become St. John Vianney Theological Seminary, a free-standing diocesan seminary with a spirituality year, pre-theologate and theologate for priestly formation. Currently a candidate for full accreditation in the Associations of Theological Schools and enjoying affiliations with the Pontifical Lateran University in Rome and Regis University, this theological seminary serves dioceses throughout the Heartland and Rocky Mountain West.
