Opus Dei membership is open to anyone and everyone, independently of talents, abilities or social standing. It is God who gives the vocation and in practice one finds people of all kinds among the members. When Opus Dei has had time to grow in a country, the social cross-section of members will correspond closely to that of Catholics in the country in question. A principal aim of Opus Dei is to promote the message that every person is called by God to be a saint, no matter what value society may place on his or her occupation and social position.
