SOCIAL OUTREACH
The presence of the laity in social life is characterized by service, the sign and expression of love, which is seen in the areas of the family, culture, work, economics and politics according to specific aspects.

...Lay men and women express the truth of their faith and, at the same time, the truth of the Church's social doctrine, which fully becomes a reality when it is lived concretely in order to resolve social problems. In fact, the credibility of this social doctrine comes more immediately from the witness of action than from its internal consistency or logic[1153].
