Service and Justice
Accordingly, peace is also the fruit of love, for love goes beyond what justice can achieve. Gaudium et Spes (The Church in the Modern World), Vatican II, 1965 #78.
Mindful of the words of the Lord: “By this all will know that you are my disciples, if you have love for one another”(Jn. 13:35), Christians can yearn for nothing more ardently than to serve the people of this age successfully with increasing generosity. Holding loyally to the Gospel, enriched by its resources, and joining forces with all who love and practice justice, they have shouldered a weighty task here on earth and they must render an account of it to him who will judge all people on the last day.
