Preaching and extending Christ’s Kingdom is the ideal that inspires, stimulates, directs, and shapes the apostolic purposes of the Legion of Christ and the Regnum Christi Movement. Their ideal is to make Christ reign in hearts and societies, to transform men according to the ideal of the New Man in Christ, and to create the civilization of love and justice.

The Legion of Christ and Regnum Christi seek to collaborate with the local churches by lending help and support to the bishops and parish priests as they carry out their diocesan pastoral programs, and by contributing the charism they have received from God, for the good of the Church.

Working with lay people is an essential part of the Legion’s apostolic methodology. The Legionaries carry out their apostolate above all with Regnum Christi members, forming them in human and Christian virtues, serving them with their priestly ministry, launching them in pastoral action, uniting efforts in their shared mission, and thus spurring on a great variety of works at the service of the Church. Apostolates have often arisen as a response to concrete needs or upon the initiative of the lay people themselves. Thus, not all of the apostolates have the same institutional relationship with the Legion of Christ and Regnum Christi.

The most important fields of their apostolic work are: education, youth and family ministry, evangelization (especially in the mission territory of Quintana Roo), and social work. In all of these areas, they pay special attention to building up a new culture of esteem and support for woman. In the past few months there has also been a significant growth in the area of forming diocesan priests and in mass media
