Nostra Aetate’s affirmation of the Church’s “esteem” for Muslims is warranted by a number of different points. Muslims adore the one God whom Christians also worship, reverencing many of the same attributes. They reverentially submit to that God, linking themselves to Abraham. They adore Jesus and are devoted to Mary. The passage ends with this striking sentence: “Finally, they value the moral life and worship God especially through prayer, almsgiving and fasting.”
On the basis of these commonalities, the ecumenical council urges Christians and Muslims to work together toward “mutual understanding” and the common good of humanity, expressed in peace, freedom, and moral rectitude. This is a profound and prudently limited affirmation of the prospects of interreligious dialogue. There is no little space for agreement or for mutual exchange among Muslims and Christians. The divine attributes constitute one such area of agreement; common connections to Abraham and esteem for Mary and Jesus constitute an area where there are more starkly different views in play, but nonetheless some common ground. These, it seems, are the ground of “mutual understanding.” Nonetheless, mutual understanding on these issues is not agreement: the document asks of Catholics an earnest attempt to comprehend the other religion, not to concur with it.
This is in keeping with the largely social agenda in which Nostra Aetate urges Catholics to collaborate with Muslims. On the basis of a shared moral life and reverence for the one God, the cultural and human-centered agenda between the two faiths is accessible and desirable. Is this a sufficient basis for interreligious dialogue, or would the document’s critics argue that it does not defend vigorously enough the potential for agreement on contested theological issues?
