Opus Dei aims to encourage people of every sector of society to desire holiness in the midst of the world. In other words, Opus Dei proposes to help ordinary citizens like yourself to lead a fully Christian life, without modifying their normal way of life, their daily work, their aspirations and ambitions.
As I wrote years ago, you could say that Opus Dei is as old and as new as the Gospel. It intends to remind Christians of the wonderful words of Genesis: God created man to work. We try to imitate the example of Christ, who spent almost all his life on earth working as a carpenter in a small town. Work is one of the highest human values and the way in which men contribute to the progress of society. But even more, it is a way to holiness…
Opus Dei is an international lay organisation to which a certain number of secular priests belong, although they are a small minority. Its members are people who live in the world and hold normal jobs. They do not join Opus Dei to give up their job. On the contrary, what they look for in the Work is the spiritual help they need to sanctify their ordinary work. Thus their work becomes a means to sanctify themselves and help others to do the same thing. They do not change their status. They continue being single, married, widowed or priests. What they try to do is serve God and their fellow men in their own state in life. Opus Dei is not interested in vows or promises. It asks its members to make an effort to practise human and Christian virtues, as children of God, despite the limitations and errors that are inevitable in human life. (Conversations, 24)
