Blessed are the peacemakers, for they will be called children of God (Mt 5:9)
Political and social unrest arises from injustice, whether real or perceived. Peace, on the other hand, is the fruit of justice, when all the members of a society receive what is their due. In our moral life, too, when we have a clear understanding of moral principles and habitual control of our emotions and our actions so that we do always what we ought to do, we are at peace with ourselves. St. Augustine was right when he defined peace as the tranquility of order.
To have order there must be some principle to base the order on. Students in a class can be ordered according to their age, or their size, or their grades, or by the alphabet. If we are to accomplish anything worthwhile our daily actions must be ordered to some goal: to making money, to becoming a lawyer, to caring for our family.
Christ has given us one goal to which we must subordinate everything else: holiness. Seek first the kingdom of God and his holiness. (Mt 6:33) To be holy is to be godlike, that is, to be perfect even as our heavenly Father is perfect (Mt 5:48). St. John tells us that God is love (1Jn 4:8) and Christ has told us how we are to love if we are to be holy and grow in perfection: Love one another as I have loved you. Greater love than this no one has than to lay down his life for his friends. You are my friends (Jn 15:12-13). To love as Christ loved us is the ultimate goal we must pursue in life. Christ-like love is the ideal we use to establish right order on all our actions and to be holy as our heavenly Father. If we are going to be a doctor or lawyer, we must be holy in our profession. Therefore, if we are in business to make a profit, it must be a just profit and we must use our profits for noble purposes and not let riches and the craving for wealth be our downfall. The psalmist is right: Those who love your law enjoy abundant peace (Ps 119:165).
For we believe that God is our Father. We pray that his will be done on earth as it is in heaven because his law or commandment to love points out the way we must follow if we are to enjoy our lives and find true peace. I think thoughts of peace, not of affliction (Jr 29:31), God tells us through the prophet Jeremiah.
When, therefore, we open our hearts to the Holy Spirit we share Gods life and enjoy the fruits of the Spirit: charity, joy and peace.
We live in a sinful world but our Lord, sending his disciples on their first missionary journey told them: When you go into a house, wish the owner of the house peace. If he is a peaceable man, your peace will rest on him. If not it will come back to you (Mt 10:13). It will not be lost. If our efforts are rebuffed, our peace returns to us. For as long as we have done our best we know God is pleased with us so we have nothing to worry about and we are at peace.
Christ has told us that one man sows, another man reaps (Jn 4:38). We should not, therefore, judge the value of our work by its apparent success or failure. Our efforts may end in apparent failure, but we know God does not judge our work by its success but by our honest efforts to bring about his kingdom on earth, a kingdom of justice, peace and love (Preface for the Feast of Christ the King). When we love God and work selflessly for him, no one can take his peace and his joy from us. That is why the peacemakers are blessed and shall be called the children of God.
