The Basilian Order of the Most Holy Saviour (Latin: Ordo Basilianus Sanctissimi Salvatoris; French: Ordre Basilien Salvatorien; also known as the Basilian Salvatorian Order and the Salvatorian Fathers) is an Eastern Catholic religious order of the Melkite Greek Catholic Church. The name derives from its motherhouse, the Holy Saviour Monastery (Arabic: دير المخلص, translit. Deir el Moukhalles; French: Couvent St. Sauveur), at Joun in Chouf near Sidon, Lebanon.
The order was founded in 1683 by Euthymios Saifi, bishop of Saida, with the aim of supporting pastoral and missionary activities by well-educated Melkite clergy, choosing for them the rule of Saint Basil. Saifi started to gather some monks in his episcopal residence, but it soon became too small for the community. In 1685 a miracle was reported during a pastoral visit of Euthymios Saifi to the village of Joun and thus some monks were sent to live in a farm near Joun. In 1710 Saifi succeeded in buying the farm and in 1711 the first building of the Holy Saviour monastery was erected.
The order was cited by Pope Benedict XIV in 1743 in the encyclical Demandatam, and on 20 April 1751 the Pope sent them a letter urging them to fully follow the Byzantine rite rejecting the Latinizations introduced by Cyril Tanas against the wishes of Rome. Their specific rules (constitutions) were formally drafted and approved only in 1934.
