In October 2007, Muslim religious leaders released the letter "A Common Word Between US and You" proposing the two commandments as expressing the most basic attitudes, values, and practices shared by the sister religions; shortly after, leaders from a wide spectrum of Christian traditions responded with the letter "Loving God and Neighbor Together" welcoming the initiative. For all the good will, the exchange did leave questions, particularly whether Christians and Muslims mean the same thing when they profess love of God and neighbor. Here religious scholars and political leaders from Muslim and Christian countries discuss invitation and response, Muslim perspectives, Christian perspectives, frequently asked questions, and the political significance.
