The Legionaries of Christ and Regnum Christi members serve the Church as an expression of their love for Christ, since Christ identified himself with the Church. In fact, Regnum Christi only exists in the Church, for the Church, and at the service of the Church’s supernatural and human mission.

Legionaries and Regnum Christi members strive to work alongside diocesan bishops and priests, as well as the many other congregations, institutions, movements, and Catholic associations that contribute to the beauty of the Church. All are united together in the Church’s common mission of bringing Christ to the world.

In their love for the Church, Regnum Christi members aim to work in the most effective way possible, both in depth and in scope, so as to help establish the Kingdom of Christ in society. They work with uncompromising loyalty to the Magisterium of the Church and in full communion with its pastors.
