 The present Arabic text of this liturgy is a translation from the Bohairic Coptic version.The other group of the Liturgies of Saint Basil includes the Greek version used in the Byzantine Rite, the older Armenian version known as "Liturgy of Saint Gregory the Illuminator" and an ancient Syriac version.H.Engberding in 1931 suggested that these three versions derives from a lost common source (Ω-BAS) and his conclusions were widely accepted by scholars.
