The faithful of Opus Dei pray daily for all those who in one way or another have helped or are helping the Prelature carry out its mission in the service of the Church. Also at certain times during the year, priests of the Prelature offer Holy Mass for the souls of deceased Cooperators.
The Holy See has granted to Catholic Cooperators a plenary indulgence (under the usual conditions established by the Church) on specific feasts in the Church and anniversaries of Opus Dei, as well as on the date of their appointment as Cooperators.
They can also receive a partial indulgence in various circumstances; for example, when attending an activity of spiritual formation.
