In his chapter "Modern Democracy" of Memory and Identity Pope Blessed John Paul II shows that freedom and morality go together saying that "...a State of law accomplishes the purpose of every democracy: that of forming a society of free citizens who jointly pursue the common good." p.132
"...Essentially, the Law [of Israel] consisted of the Decalogue: the ten commandments, the ten principles of conduct, without which no human community, no nation, not even the international community, can function...
"...The divine law of the Decalogue is also binding, as natural law, for those who no not accept Revelation: do not kill, do not steal, do not bear false witness, honor your father and your mother...Each of these commands from the Sinai code seeks to defend a fundamental good of human and social life. If such a law is placed in doubt, ordered human society becomes impossible and mans's moral existence is put at risk. Moses is not the author of the tablets of the Commandments which he brought down from the mountain. Rather, he is the servant and the spokesman of the Law given to him by God on Sinai." p. 133
This text reminded me of His Holiness Pope Benedict XVI's historic address at the Synagogue of Rome last year in which he showed the fundamental agreement between Jewish and Catholic moral teachings. Here is the relevant text.
5. Many lessons may be learnt from our common heritage derived from the Law and the Prophets. I would like to recall some of them: first of all, the solidarity which binds the Church to the Jewish people "at the level of their spiritual identity", which offers Christians the opportunity to promote "a renewed respect for the Jewish interpretation of the Old Testament" (cf. Pontifical Biblical Commission, The Jewish people and their Sacred Scriptures in the Christian Bible, 2001, pp. 12 and 55); the centrality of the Decalogue as a common ethical message of permanent value for Israel, for the Church, for non-believers and for all of humanity; the task of preparing or ushering in the Kingdom of the Most High in the "care for creation" entrusted by God to man for him to cultivate and to care for responsibly (cf. Gen 2: 15).
6. In particular, the Decalogue the "Ten Words" or Ten Commandments (cf. Ex 20: 1-17; Dt 5: 1-21) which comes from the Torah of Moses, is a shining light for ethical principles, hope and dialogue, a guiding star of faith and morals for the people of God, and it also enlightens and guides the path of Christians. It constitutes a beacon and a norm of life in justice and love, a "great ethical code" for all humanity. The "Ten Commandments" shed light on good and evil, on truth and falsehood, on justice and injustice, and they match the criteria of every human person's right conscience. Jesus himself recalled this frequently, underlining the need for active commitment in living the way of the Commandments: "If you wish to enter into life, observe the Commandments" (Mt 19: 17). From this perspective, there are several possible areas of cooperation and witness. I would like to recall three that are especially important for our time.
The "Ten Commandments" require that we recognize the one Lord, against the temptation to construct other idols, to make golden calves. In our world there are many who do not know God or who consider him superfluous, without relevance for their lives; hence, other new gods have been fabricated to whom man bows down. Reawakening in our society openness to the transcendent dimension, witnessing to the one God, is a precious service which Jews and Christians can and must offer together.
The "Ten Commandments" call us to respect life and to protect it against every injustice and abuse, recognizing the worth of each human person, created in the image and likeness of God. How often, in every part of the world, near and far, the dignity, the freedom and the rights of human beings are trampled upon! Bearing witness together to the supreme value of life against all selfishness, is an important contribution to a new world where justice and peace reign, a world marked by that "shalom" which the lawgivers, the prophets and the sages of Israel longed to see.
The "Ten Commandments" call us to preserve and to promote the sanctity of the family, in which the personal and reciprocal, faithful and definitive "Yes" of man and woman makes room for the future, for the authentic humanity of each, and makes them open, at the same time, to the gift of new life. To witness that the family continues to be the essential cell of society and the basic environment in which human virtues are learned and practised is a precious service offered in the construction of a world with a more human face.
7. As Moses taught in the Shema (cf. Dt 6: 5; Lev 19: 34) and as Jesus reaffirms in the Gospel (cf. Mk 12: 19-31), all of the Commandments are summed up in the love of God and loving-kindness towards one's neighbour. This Rule urges Jews and Christians to exercise, in our time, a special generosity towards the poor, towards women and children, strangers, the sick, the weak and the needy. In the Jewish tradition there is a wonderful saying of the Fathers of Israel: "Simon the Just often said: The world is founded on three things: the Torah, worship, and acts of mercy" (Avoth 1: 2). In exercising justice and mercy, Jews and Christians are called to announce and to bear witness to the coming Kingdom of the Most High, for which we pray and work in hope each day.
8. On this path we can walk together, aware of the differences that exist between us, but also aware of the fact that when we succeed in uniting our hearts and our hands in response to the Lord's call, his light comes closer and shines on all the peoples of the world. The progress made in the last forty years by the International Committee for Catholic-Jewish Relations and, in more recent years, by the Mixed Commission of the Chief Rabbinate of Israel and of the Holy See, is a sign of our common will to continue an open and sincere dialogue. Tomorrow here in Rome, in fact, the Mixed Commission will hold its ninth meeting, on "Catholic and Jewish Teaching on Creation and the Environment"; we wish them a profitable dialogue on such a timely and important theme.
9. Christians and Jews share to a great extent a common spiritual patrimony, they pray to the same Lord, they have the same roots, and yet they often remain unknown to each other. It is our duty, in response to God's call, to strive to keep open the space for dialogue, for reciprocal respect, for growth in friendship, for a common witness in the face of the challenges of our time, which invite us to cooperate for the good of humanity in this world created by God, the Omnipotent and Merciful...
