Muslim Affairs

The Church regards with esteem also the Moslems. They adore the one God, living and subsisting in himself, merciful and all-powerful, the Creator of heaven and earth, who has spoken to men; they take pains to submit wholeheartedly to even his inscrutable decrees, just as Abraham, with whom the faith of Islam takes pleasure in linking itself, submitted to God. Though they do not acknowledge Jesus as God, they revere him as a prophet. They also honor Mary, his virgin Mother; at times they even call on her with devotion. In addition, they await the day of judgment when God will render their deserts to all those who have been raised up from the dead. Finally, they value the moral life and worship God especially through prayer, almsgiving and fasting. 

Since in the course of centuries not a few quarrels and hostilities have arisen between Christians and Moslems, this sacred synod urges all to forget the past and to work sincerely for mutual understanding and to preserve as well as to promote together for the benefit of all mankind social justice and moral welfare, as well as peace and freedom.

  • John Paul II, address to the Catholic community of Ankara, Turkey, November 29, 1979
    “My brothers, when I think of this spiritual heritage (Islam) and the value it has for man and for society, its capacity of offering, particularly in the young, guidance for life, filling the gap left by materialism, and giving a reliable foundation to social and juridical organization, I wonder if it is not urgent, precisely today when Christians and Muslims have entered a new period of history, to recognize and develop the spiritual bonds that unite us, in order to preserve and promote together for the benefit of all men, ‘peace, liberty, social justice and moral values’ as the Council calls upon us to do (Nostra Aetate 3).”
  • John Paul II, address to representatives of Muslims of the Philippines, February 20, 1981
    “I deliberately address you as brothers: that is certainly what we are, because we are members of the same human family, whose efforts, whether people realize it or not, tend toward God and the truth that comes from him. But we are especially brothers in God, who created us and whom we are trying to reach, in our own ways, through faith, prayer and worship, through the keeping of his law and through submission to his designs. …”
  • “Dear Muslims, my brothers: I would like to add that we Christians, just like you, seek the basis and model of mercy in God himself, the God to whom your Book gives the very beautiful name of al-Rahman, while the Bible calls him al-Rahum, the Merciful One.”
  • John Paul II, address to the bishops of North Africa on their ad limina visit, Rome, November 23, 1981
    “One of the essential characteristics of the life of the Church in Maghreb is, in fact, to be invited to enter upon a constructive Islamic-Christian dialogue. I am anxious to encourage you along this difficult way, where failure may occur, but where hope is even stronger. To maintain it, strong Christian convictions are necessary. …
  • “But it can never be said enough that such a dialogue is in the first place a question of friendship; one must know how to give dialogue the time for progress and discernment. That is why it is surrounded by discretion out of a concern to be considerate with regard to the slowness of the evolution of mentalities.”
  • John Paul II, address to the participants in a symposium on “Holiness in Christianity and in Islam,” Rome, May 9, 1985
    “All true holiness comes from God, who is called ‘The Holy One’ in the sacred books of the Jews, Christians, and Muslims. Your holy Qur’an calls God ‘Al-Quddus,’ as in the verse: ‘He is God, besides whom there is no other, the Sovereign, the Holy, the (source of) Peace’ (Qur’an 59, 23). The prophet Hosea links God’s holiness with his forgiving love for mankind, a love which surpasses our ability to comprehend: ‘I am God, not man; I am the Holy One in your midst and have no wish to destroy’ (Ho 11:9). In the Sermon on the Mount, Jesus teaches his disciples that holiness consists in assuming, in our human way, the qualities of God’s own holiness which he has revealed to mankind: ‘Be holy, even as your heavenly Father is holy’ (Mt 5:48).
  • John Paul II, address to representatives of the Muslims of Belgium, May 19, 1985
    “It is a good thing to come to understand each other by learning to accept differences, by overcoming prejudices in mutual respect, and by working together for reconciliation and service to the lowliest. This is a fundamental dialogue which must be practiced in neighborhoods, in places of work, in schools. This is the dialogue which is proper to believers who live together in a modern and pluralistic society.
  • “It has not been granted to us that we form a single community; this is, rather, a test which has been imposed upon us. In confronting this situation, allow me to repeat the advice of the Apostle Paul: ‘Those who have placed their faith in God should set their hearts on the practice of what is good’ (Tt 3:8).
  • John Paul II , address to the young Muslims of Morocco, August 19, 1985
    “I believe that we, Christians and Muslims, must recognize with joy the religious values that we have in common, and give thanks to God for them. Both of us believe in one God, the only God, who is all justice and all mercy; we believe in the importance of prayer, of fasting, of almsgiving, of repentance and of pardon; we believe that God will be a merciful judge to us all at the end of time, and we hope that after the resurrection He will be satisfied with us and we know that we will be satisfied with him.
  • “Loyalty demands also that we should recognize and respect our differences. Obviously the most fundamental is the view that we hold onto the person and work of Jesus of Nazareth. You know that, for Christians, Jesus causes them to enter into an intimate knowledge of the mystery of God and into the filial communion by His gifts, so that they recognize Him and proclaim Him Lord and Savior.
  • “Those are the important differences which we can accept with humility and respect, in mutual tolerance; this is a mystery about which, I am certain, God will one day enlighten us.
  • “Christians and Muslims, in general we have badly understood each other, and sometimes, in the past, we have opposed and often exhausted each other in polemics and in wars.
  • “I believe that today, God invites us to change our old practices. We must respect each other, and we must stimulate each other in good works on the path of God.
  • John Paul II, address to a group of Christians, Jews and Muslims, February 26, 1986
    “Both the Bible and the Qur’an teach that mercy and justice are two attributes most characteristic of God. He, ‘the Just One,’ ‘the Merciful, the Compassionate,’ can bring about these same qualities in mankind, if only we open our hearts to allow him to do so. He wants us to be merciful toward each other. Along this path there are new solutions to be found to the political, racial and confessional conflicts which have plagued the human family throughout history.
  • “I wish to encourage you in your efforts. In today’s world, it is more important than ever that people of faith place at the service of humanity their religious conviction, founded on the daily practice of listening to God’s message and encountering him in prayerful worship. My prayers and hopes are with you as you pursue your reflection on the God of mercy and justice, the God of peace and reconciliation!”
  • John Paul II at Assisi, October 27, 1986, prays for peace together with representatives of the world’s religions
  • John Paul II, address to the delegation of the World Islamic Call Society, Rome, 15 January 1990
    “… Both Christians and Muslims are called to defend the inviolable right of each individual to freedom of religious belief and practice. There have been in the past, and there continue to be in the present, unfortunate instances of misunderstanding, intolerance and conflict between Christians and Muslims, especially in circumstances where either Muslims or Christians are a minority or are guest workers in a given country. It is our challenge as religious leaders to find ways to overcome such difficulties in a spirit of justice, brotherhood and mutual respect. …”
  • John Paul II, to H. E. Mohammed Sayed Tantawi, Grand Sheikh of al-Azhar, Cairo, February 24, 2000
    “I express my great gratitude for this opportunity and I greet all the eminent scholars gathered here. I am convinced that the future of the world depends on the various cultures and on interreligious dialogue.”
  • John Paul II, at the International Airport, Amman, Jordan, March 20, 2000
    “Building a future of peace requires an ever more mature understanding and ever more practical cooperation among the peoples who acknowledge the one true, indivisible God, the Creator of all that exists. The three historical monotheistic religions count peace, goodness and respect for the human person among the highest values. I earnestly hope that my visit will strengthen the already fruitful Christian-Muslim dialogue which is being conducted in Jordan, particularly through the Royal Interfaith Institute.”
  • John Paul II, to the ambassador of the Arab Republic of Egypt, September 7, 2000
    “In a world deeply marked by violence, it is bitterly ironic that even now some of the worst conflicts are between believers who worship the one God, who look to Abraham as a holy patriarch and who seek to follow the Law of Sinai. Each act of violence makes it more urgent for Muslims and Christians everywhere to recognize the things we have in common, to bear witness that we are all creatures of the one merciful God, and to agree once and for all that recourse to violence in the name of religion is completely unacceptable. Especially when religious identity coincides with cultural and ethnic identity it is a solemn duty of believers to ensure that religious sentiment is not used as an excuse for hatred and conflict. Religion is the enemy of exclusion and discrimination; it seeks the good of everyone and therefore ought to be a stimulus for solidarity and harmony between individuals and among peoples”
  • John Paul II, Novo Millennio Ineunte 55, January 6, 2001
    “It is in this context (of openness to God’s grace) also that we should consider the great challenge of interreligious dialogue to which we shall still be committed in the new millennium, in fidelity to the teachings of the Second Vatican Council (Cf. Second Vatican Council, declaration Nostra Aetate). . . . This dialogue must continue. In the climate of increased cultural and religious pluralism which is expected to mark the society of the new millennium, it is obvious that this dialogue will be especially important in establishing a sure basis for peace and warding off the dread specter of those wars of religion which have so often bloodied human history. The name of the one God must become increasingly what it is: a name of peace and a summons to peace.”
  • John Paul II, address on his Visit to the Umayyad Great Mosque, May 6, 2001 – first pope to enter a mosque
    “It is in mosques and churches that the Muslim and Christian communities shape their religious identity, and it is there that the young receive a significant part of their religious education. What sense of identity is instilled in young Christians and young Muslims in our churches and mosques? It is my ardent hope that Muslim and Christian religious leaders and teachers will present our two great religious communities as communities in respectful dialogue, never more as communities in conflict. It is crucial for the young to be taught the ways of respect and understanding, so that they will not be led to misuse religion itself to promote or justify hatred and violence. Violence destroys the image of the Creator in his creatures and should never be considered as the fruit of religious conviction.
  • “I truly hope that our meeting today in the Umayyad mosque will signal our determination to advance interreligious dialogue between the Catholic Church and Islam. This dialogue has gained momentum in recent decades; and today we can be grateful for the road we have traveled together so far.
