The mission of the Society of the Catholic Apostolate (SAC) is in line with the mission of Jesus Christ and of the Church - “to revive faith and re-enkindle charity of the entire People of God and to spread the faith and charity in the world, so that soon there may be but one flock and one shepherd” (John 10,16).

In general, the mission of the SAC is to increase the collaboration among the members of the Church, that is, among the diocesan priests, the male and female religious, and the laity, to fully and efficiently fulfil the apostolic tasks.

The Society of the Catholic Apostolate (SAC) is a core community of the Union of Catholic Apostolate (UAC). As such it shares responsibility with others for the spirituality and the apostolic effectiveness of the whole Union. In many ways, the mission of the SAC is realised in concrete ways through the UAC.
