Grégoire Haddad in Arabic (25 September 1924 – 23 December 2015) was, from 1968 to 1975, Archeparch of the Melkite Greek Catholic Archeparchy of Beirut and Jbeil. He was known as the "Red Bishop of Beirut" promoting a secular "social movement" and a platform of rapprochement between Muslims and Christians with the onslaught of the Lebanese Civil War. He reinforced his controversial viewpoints through further secular movements and through Afaq magazine, which he founded. In 1975 under pressure from the Holy See, he resigned from active religious duty. Since his resignation, he became an emeritus archbishop without holding an actual diocese in Lebanon.
