The Legionaries of Christ, by their religious consecration, contribute the testimony of their self-giving to Jesus Christ and their complete availability for the fulfillment of the common mission. By their condition as priests, they make present Christ the Priest and Good Shepherd through preaching, administering the sacraments and spiritual direction. In communion with all, they collaborate in the integral formation, direction, and apostolic projection of the associated lay faithful, promoting the fullness of their baptismal vocation and Christian leadership; and they establish institutions and initiate actions that can most contribute, in depth and in extent, to building up the Kingdom of Christ in society.”
