The Cooperators of Opus Dei are men and women – Catholics and non-Catholics – who are not incorporated into the Opus Dei Prelature, but who collaborate with the faithful of the Prelature in the various educational, charitable and cultural activities.

The main contribution of the Cooperators towards these ventures is that of their prayer, but they can also help through their work or financially. They receive the spiritual goods the Church grants to those who assist Opus Dei. These include indulgences which the Cooperators, provided they observe the conditions established by the Church, can gain on specific days of the year, and when out of devotion they renew their obligations as Cooperators. From the Opus Dei Prelature they also receive the spiritual help of the prayers of all its members
