In 1982 Salibi finalised his book, "The Bible Came from Arabia", during the Israeli invasion of Lebanon. It was translated into German at the same time as the original English version was being published in London. Salibi wrote subsequent works on biblical issues using the same etymological and geographic methodology. Some of his books are today considered classics, notably "A House of Many Mansions: The History of Lebanon Reconsidered" (1988) and "The Modern History of Jordan" (1993). In 1994, Salibi helped found the "Royal Institute for Inter-Faith Studies" in Amman, Jordan, and became its director from 1997 until 2004, following his retirement from AUB. He was associated as a consultant with the "Druze Heritage Foundation". He retired from the Department of History and Archeology at the American University of Beirut in 1998, and became professor emeritus. He moved to Amman in the early 1990s and became director of the Institute for Interfaith Studies there from 1994 to 2003. He believed Lebanon's Christian community had an important role to play in building a Lebanon distinct from its Islamic ambiance, but did not share the fanaticism about Lebanon's Christian nature shown by many of his Maronite colleagues. He dismantled the foundational myths which many of Lebanon's communities were attached to, and replaced them with a complex portrait of the nation as an intricate mosaic of disparate but interconnected communities, over which no one group exerted dominance. He was strongly opposed to sectarian politics, believing that it had been the ruin of his country, and was one of the first Lebanese to remove his religious denomination ("math-hab") from the Lebanese census records. He pinned a copy of his new ID, which has 'I' for his "math-hab" outside his apartment in Ras Beirut.
