The Jewish religion is not extrinsic to us but in a certain way intrinsic to our own religion. With Judaism, therefore, we have a relationship which we do not have with any other religion. You are our dearly beloved brothers, and, in a certain way, it can be said that you are our elder brothers. Visiting a Jewish synagogue in Rome. (1986)

Science develops best when its concepts and conclusions are integrated into the broader human culture and its concerns for ultimate meaning and value. Scientists cannot, therefore, hold themselves entirely aloof from the sorts of issues dealt with by philosophers and theologians. By devoting to these issues something of the energy and care they give to their research in science, they can help others realize more fully the human potentialities of their discoveries. They can also come to appreciate for themselves that these discoveries cannot be a genuine substitute for knowledge of the truly ultimate. Science can purify religion from error and superstition; religion can purify science from idolatry and false absolutes. Each can draw the other into a wider world, a world in which both can flourish. Letter to the Reverend George V. Coyne, S.J., Director of the Vatican Observatory (1988-06-01).

God of our fathers, you chose Abraham and his descendants to bring your name to the nations: We are deeply saddened by the behavior of those who in the course of history have caused these children of yours to suffer, and, asking your forgiveness, we wish to commit ourselves to genuine brotherhood with the people of the covenant. Written prayer, placed by John Paul II into the "Wailing Wall" while visiting Jerusalem. (2000)

We Christians joyfully recognize the religious values we have in common with Islam. Today I would like to repeat what I said to young Muslims some years ago in Casablanca: 'We believe in the same God, the one God, the living God, the God who created the world and brings his creatures to their perfection.' 1999-05-05
