We the Muslim and Christian participants meeting together at Yale for the historic A Common Word conference denounce and deplore the recent threat made against His Majesty King Abdullah bin Abd Al-Aziz the Custodian of the Two Holy Mosques for having sponsored the recent important interfaith gathering in Madrid. Such threats are directed not towards His Majesty alone but against all of those who work towards peace through dialogue and cooperation. Dialogue is not a departure from faith, it is a legitimate means of its expression, and an essential tool in the quest for the common good.
