About us


The Immaculate Conception School of Theology, Vigan City, Ilocos Sur trains future pastors who will preach the Word of God, minister to the sacramental needs of God’s people, build, guide and lead the communities thus nurtured on the Word and the Sacrament. The seminary educates these future pastors to be knowledgeable, competent and perceptive professionals, and forms them to be mature men, prayerfully dedicated to God and apostolically committed to His kingdom.

The seminary prepares, evaluates, judges and recommends candidates for the diocesan priesthood for the Archdioceses and Dioceses of the ecclesiastical provinces of Northern Luzon.

The seminary forms and educates seminarians according to the goals and aims, the policies and regulations of the Church and of the seminary.

The seminary is guided by the spirit of the Second Plenary Council of the Philippines in January 1991. In line with the Council’s call for a Community of Disciples, following the Lord Jesus in His ministry to all, especially to the poor, we orient our community activities, our apostolate and studies towards the formation of Basic Ecclesial Communities both among ourselves and in our surroundings. Pertinent to seminary formation, the Council decrees:

“The Second Vatican Council reminds us that the formation of priests is of critical importance, because on it depends the success of the renewal of the whole Church. The journey of the priestly vocation begins with a call by Jesus, a drawing to his person, a desiring to do good to other.”

“Special attention should be given to the spiritual, intellectual, psychological, disciplinary and pastoral aspects of formation. In these areas as well as in the formation to a mature socio-affective and healthy sexuality, Priest-formators and selected mature lay members of the Christian community should collaborate. Relevant formation given in our seminaries today should take into account the depressing poverty of large portions of society, the emergence of a concerned and fast maturing laity, the coming together of numerous small ecclesial communities and the unmistakable basic hunger of all for the Spirit.”
