Polls and practical experience both point to a widespread ignorance of the principles of Catholic Social Teaching among Catholic lay people in the United States. A greater emphasis on education in social doctrine is evidently required. One component of this should be to call attention to the eight areas of lay apostolic activity identified by Pope John Paul II in Christifideles laici: promoting the dignity of the human person; fostering respect for the right to life; defending freedom of conscience and religious freedom; protecting and encouraging marriage and family life; participating in public life; placing the individual at the center of socioeconomic life; and the evangelization of culture. Of particular importance in motivating lay people to engage in apostolic activity is the inculcation of the idea of personal vocation. And highly relevant in a wealthy society like ours is the question of lifestyle. The chapter therefore concludes by calling for an updated understanding of the virtue of temperance as it relates to social teaching.
