Gabriel of Blaouza was appointed and consecrated Maronite bishop of Aleppo by Patriarch George Rizqallah Beseb'ely in 1663.
In 1672, he was chosen by Pope Clement X to deliver the pallium to the new patriarch Estephan El Douaihy, whom he became a valuable employee.
In 1673, while continuing to administer his diocese, he founded a monastery north of Beirut, where he lived most of the rest of his life.
The first Mass was celebrated in the newly erected church of his order at the Monastery of Mar Chaya on August 15, 1700.
[3] Blaouza, however, received the pallium only in October 1705 and died suddenly on the eve of the Solemnity of All Saints' Day of the same year.
