Metzger worked to encourage friendly relationships with other religious communities. One idea that Metzger proposed was the establishment of a religious United Nations in Jerusalem. He first advocated this in late 2004 after mediating a highly publicized dispute between Jerusalem Haredim and the Armenian Christian community. Under Metzger's plan, the new body would contain representatives of the world's religions, as opposed to nations. Metzger has also suggested that the Dalai Lama could lead the assembly. The Dalai Lama was reportedly very excited at the idea, and pledged to help Metzger realize his plan. Other supporters include Frederico Major, the co-president of the Alliance for Civilizations, a Spanish lobby group for international conflict resolution.
