The Neocatechumenal Way is a Christian initiation and organization Catholic. The statutes approved by the Holy See define it as an itinerary of permanent Catholic formation, catechumenal, and “neocatechumenal” or post-baptismal catechumenal, at the service of catechesis and dependent on the bishops, endowed with public juridical personality. Its members are popularly known in Spain by the name of “kikos”, due to the name of its initiator, the layman Kiko Argüello, who together with Carmen Hernández and the Italian priest Mario Pezzi formed the Itinerant Team Responsible Internationally of the movement.​

The Neocatechumenal Way was created in the 1960s in the neighborhood of Palomeras, on the outskirts of Madrid. Its statutes were initially approved on June 29, 2002, temporarily for five years ad experimentum, by Pope John Paul II. Subsequently, at the beginning of 2008, the decree was issued in which the statutes were definitively approved, and the same year, Cardinal Stanisław Ryłko, president of the Pontifical Council for the Laity, delivered the decree of final approval of the statutes.
