United in Christ members share in the mission of the Church of bringing Good News of Salvation to the world through proclamation witness and Service .
Members, by their very presence and life manifest to the world the living presence of Jesus and witness to the eschatological life.
Prayerful union with God, continuous renunciation of worldliness for the sake of His Kingdom, an exemplary life lived in the light of the Gospel, and service lovingly rendered to the mankind are the primary responsibilities in a member's daily life and ministry.
In carrying out apostolic works, members adapt their lifestyles to the place, time, culture, spiritual richness, language and needs of the people whom they are ministering.
