The Archdiocese of Byblos & Botris (Mount Lebanon) prides itself with apostolic roots. The first bishop to preside over the archbishopric of Byblos was Saint Marc the Evangelist. And the first bishop on the archbishopric of Botris was Saint Silas (Silouan). Saint Peter set these two bishops during his journey, together with the apostles, from Jerusalem to Antioch after the martyrdom of Saint Stephen.
In the beginning these two dioceses were under the jurisdiction of the archdiocese of Tyre. The fourth Ecumenical Council (451 A.D.) confirmed this legal situation by freeing these two bishoprics from the dominance of the bishop of Beirut-who had subdued them to his jurisdiction and by declaring the legitimacy of Tyre’s litigate.

    The orthodox population in the area of the present archdiocese increased in number along the following centuries mainly due to migrations, persecutions, invasions and wars of different characters. Byzantine wars, Crusades, Mamluk invasions—all contributed in the constant demographic reshaping of Mount Lebanon’s area—which now was officially subdued under the jurisdiction of Beirut and become known as the Archdiocese of Beirut and all Lebanon.

    Starting from 1861, the number of the Orthodox commenced rising again in the province of Mount Lebanon due to the increased migration from Damascus after the wave of massacres that the Christians suffered in these areas (during which St. Joseph of Damascus was martyred). All these demographic modifications made the archdiocese of Beirut and all Lebanon vast and hard for pastoral management. 

    Since 1970, this archdiocese is under the vigilant care of Metropolitan George who is now residing in Brumana (originally the archdiocese' summer residence) after the destruction of the original archdiocese headquarters in the town of Hadath during the Lebanese civil war.
