Opus Dei in society refers to the social mission, general social strategy, social activities, work, relationship with politics and other aspects of Opus Dei. Mission in society and general strategy According to Catholic officials and scholars, Opus Dei is God's Work performing a divine operation in society which mobilises Christians to sanctify secular realities from within. Opus Dei does not act as a group, they say. It is a spiritual, catechetical agency of the Catholic Church in charge of forming people so they can act with personal responsibility "to put Christ on top of all human activities," as their founder says. Escriva said that Opus Dei evangelises people of all social classes: "Out of a hundred souls, we are interested in one hundred."

So that the sanctification of society can take place through sanctification of work, the Opus Dei provides "professional formation." This stresses hard work, cultural and professional development, human warmth and refinement, ethical behaviour, respect for freedom and pluralism, personal and collective humility, and personal prayer as the highest priority in one's daily schedule. The main strategy, according to Escrivá's teaching, is that each Christian must strive to become a "canonizable saint", another Christ redeeming all men and women, and thus also a responsible citizen who works for the common good. Because if Christians are not well ordered from within, he says, if they do not put God first through a life of contemplation, they will be merely spreading their disorder to other people. "These world crises", he says, "are crises of saints." Thus, evangelization in Opus Dei is done one-on-one through its
