CCC 2105 The duty of offering God genuine worship concerns man both individually and socially. This is “the traditional Catholic teaching on the moral duty of individuals and societies toward the true religion and the one Church of Christ.”¹ By constantly evangelizing men, the Church works toward enabling them “to infuse the Christian spirit into the mentality and mores, laws and structures of the communities in which [they] live.”² The social duty of Christians is to respect and awaken in each man the love of the true and the good. It requires them to make known the worship of the one true religion which subsists in the Catholic and apostolic Church.³ Christians are called to be the light of the world. Thus, the Church shows forth the kingship of Christ over all creation and in particular over human societies.⁴
