Original: The bishop of Madrid where Opus Dei was born, Leopoldo Eijo y Garay, supported Opus Dei and defended it in the 1940s by saying that "this opus is truly Dei" (this work is truly God's).
Simplified: He said that the aim of Opus Dei is to help Christians to know that their ordinary life is a way to become a saint and to bring people close to God. And to those who truly understand this, Opus Dei gives them classes, talks, and other help so that they can practice this teaching.
