What we do
Faith, formation, mission, and charity. The center of our work is the Holy Sacrifice of the Mass. From it proceed prayer, priestly formation, catechesis, the missionary apostolate, and works of charity.


- 01
Preaching and catechesis
The proclamation of Catholic doctrine and religious instruction constitute an essential part of the apostolate.
Catechesis is directed to children, youth, and adults, so that knowledge of the truth may lead to a more perfect Christian life.

- 02
Priestly ministry
Priests provide sacramental and spiritual assistance to the faithful, according to local possibilities and needs.

- 03
Missionary apostolate
Particular care is reserved for regions where priestly presence, religious instruction, and the means necessary for mission life are scarce.

- 04
Works of mercy
Christian charity extends to the spiritual and temporal needs of our neighbor.
The Pious Union assists, according to its means, the poor, the sick, children, and needy families.

Mary Queen of the Apostles International Catholic Seminary
The formation of clergy constitutes one of the primary responsibilities of the Pious Union.
The Mary Queen of the Apostles International Catholic Seminary is intended for those who desire to seriously discern a priestly vocation.
Study must be accompanied by prayer, discipline, and the progressive acquisition of priestly virtues.
The priest must be first and foremost a man of God. «The harvest truly is plenteous, but the labourers are few.» (Mt 9:37)

Disciplines of study and formation

Vocations
«Ecce ego, mitte me»
The priestly and religious vocation is a call to the consecration of one's entire life.
Numbers are not sought, but men willing to serve God with uprightness of intention, spirit of sacrifice, love for prayer, and fidelity to Catholic doctrine.
Those who seriously feel the call may contact the General Direction for an initial discernment.
The Church needs holy men.

Apostolic Missionaries Daughters of Mary Queen
Alongside the male branch operates the female branch of the Apostolic Missionaries Daughters of Mary Queen.
Their life is placed under the special patronage of the Most Holy Virgin and comprises prayer, catechesis, care for children and the sick, works of mercy, the Marian apostolate, and collaboration in missions.
External service must always proceed from union with God.

Publications
The good press in the service of truth
The Pious Union prepares and distributes catechisms, spiritual works, texts on the Holy Mass, Marian publications, editions of Sacred Scripture, and books on the Four Last Things, Angels, Sacraments, prayer, and the Holy Face of Our Lord Jesus Christ.
The written word can reach souls that the priest cannot reach in person.
