From their website:
The Apostles of Jesus Christ, Priest and Victim, is a new society of diocesan priests, founded in the Archdiocese of Chicago with the permission of Francis Cardinal George, whose charism is to sanctify its members through conformity to Christ crucified in a mission of shared charity.
Our fundamental mission is to save the greatest number of souls and to renew parish life according to the following specific means:
Reverently offering the Holy Sacrifice of the Mass, in both the ordinary and extraordinary forms, thus communicating the beauty and nobility of the Sacred Liturgy.
Zealously preaching and teaching in order to extend Christ’s universal Kingship.
Fostering sanctification of the family through the sacramental life and consecration to the Hearts of Jesus and Mary.
Forming men in their vocation to natural and spiritual fatherhood, including priestly vocations, through devotion to St. Joseph.
In our mission to save souls, which we carry out in communion with the Pope and the Bishops, we offer our lives and sufferings daily in union with Jesus, High Priest and Victim, in the Holy Sacrifice of the Mass and with Mary, our Mother in the Order of Grace.
