In 2006, Maciel was investigated by the Holy See and suspended from his ministry, initially over breaches of celibacy, and following public revelations later confirmed as sustained, over sexual abuse of minors.

After Maciel's death, and following more revelations, Pope Benedict XVI ordered an apostolic visitation of the Legion of Christ 2009.

Members from all states in life participated in that reflection, as individuals and in groups, under the guidance of officials from the Holy See.

The spirituality of Regnum Christi is Christ-centered, springing from a personal experience of Christ's love and overflowing in an ongoing and ever-deepening relationship with him.

"[3] According to the National Catholic Reporter, (at least as of 2010) members of Regnum Christi participated in study groups discussing the wisdom of Maciel's letters.

Number 8 of the Statutes of the Regnum Christi Federation explains this as "To fulfill our mission, we seek to make present the mystery of Christ who goes out to people, reveals the love of his heart to them, gathers them together and forms them as apostles and Christian leaders, sends them out and accompanies them as they collaborate in the evangelization of people and of society.

It’s a call that helps members live their baptismal commitments and fulfill the mission of being salt & light in the world.

It allows us to form a strong and rich Catholic worldview, develop our capacity to go deeper in our relationship with Christ and to “always be prepared to give an answer to everyone who asks you for the reason for your hope” (1 Peter 3:15).

Lay Regnum Christi members make Christ’s kingdom present in the world and transform daily realities with the light of the Gospel, especially in their family, professional, and social lives.

[7] The Consecrated Women of Regnum Christi are a Society of Apostolic Life and part of the Regnum Christi Federation that is made up of lay women who dedicate their lives fully to Christ through the evangelical vows of poverty, chastity and obedience lived within international communities.

They collaborate with Regnum Christi and the Church, accompanying thousands through formation of seminarians, lay leaders, teachers, students, young people and parents; preaching, offering spiritual direction, and leading courses, pilgrimages, missions and retreats in over 15 countries around the world.

They were formed on April 13, 1975 by Marcial Maciel with Álvaro Corcuera (who later became the general director of the Legionaries of Christ and Regnum Christi) as one of the founding members.

Driven by the desire of Jesus’ heart to set the world ablaze, the religious priests of the Legionaries of Christ support each other and work in communion with other Regnum Christi members in their mission to form apostles, people who let the love of Christ the King transform their hearts, their families and their world.

Through prayer, an adolescent discovers God’s presence in their heart, hears him and dialogues with him, seeks to know his will and receives strength to follow it.

In ECYD, formation is understood as a path of encounters which bring adolescents to know, accept and master themselves; to discover in Christ the full meaning of their lives, and to develop their leadership as apostles.

Accompaniment is personal attention offered on both an individual and group level in the varied circumstances of the adolescents’ lives.

Under the guidance of Cardinal Velasio De Paolis, the congregation announced the order's complete restructuring at its Extraordinary General Chapter in Rome in January 2014.

[22] Codes of conduct are established for Legionaries of Christ, Consecrated Men and Women, and for lay members who have contact with minors through Regnum Christi.

These policies and procedures are subject to the standards of accreditation of Praesidium, a specialized external third-party institution, ensuring the most demanding criteria in the creation of safe environments is met.
