Our mission and vision

Our mission is one we share with our partner, the Regina Apostolorum Pontifical Athenaeum: that is, the formation of apostles, Christian leaders (both clergy and laity) at the service of the Church who bear witness to the mystery of Christ; to create, in full communion with the magisterium of the Church, current of thought that can respond to man’s theoretic and existential questions and fill our society with the spirit of the Gospel.

The Institute strives to offer ongoing spiritual, theological, and pastoral formation to ordained ministers (without excluding candidates to the priesthood), based on the Magisterium’s teaching about ongoing formation and priestly spirituality, and fomenting the integration of doctrine and spirituality with the specific pastoral work of priests. ​

Every year, we welcome hundreds of priests from dioceses all over the world, fostering a spirit of communion, dialogue, encounter and renewal at the service of the Universal Church. 

We greatly value the richness proper to each nation and people, and strive to incarnate this multicultural aspect of the Church through the development of interpersonal relations, the sharing of experiences, and daily personal testimonies of the protagonists of the New Evangelization. 

Therefore, we are at the service of the Universal Church, helping her to respond to today’s new and increasing demands and the uncertainties of tomorrow’s society.
