The "Prelature of the Holy Cross and the Work of God", commonly known as Opus Dei, is founded.

Opus Dei is an institution of the Catholic Church that was founded in Spain in 1928 by Josemaría Escrivá. Its stated mission is to help its lay and clerical members seek holiness in their everyday occupations and societies. Opus Dei is officially recognized within the Catholic Church, although its status has evolved. It received final approval by the Catholic Church in 1950 by Pope Pius XII. Pope John Paul II made it a personal prelature in 1982 by the apostolic constitution Ut sit. While Opus Dei has received support from the Catholic Church, it is considered controversial.
