Opus Dei is a Catholic organization of people from all walks of life who want to pursue holiness in and through their ordinary activities. It was founded by St. Josemaria and represents his life's work. In its activities Opus Dei resembles a support group for pursuing holiness in the secular world: they sponsor classes about faith and doctrine, offer retreats, and members hold small informal gatherings in their homes or at the homes of their friends to talk about how to pursue holiness.

St. Josemaria was the founder of Opus Dei. His teachings are also the basis of the mission of the St. Josemaria Institute. As such, the messages of the two organizations are intertwined. However, the St. Josemaria Institute hopes to promote St. Josemaria's valuable teachings to the general public regardless of people's relationship to Opus Dei.
