Coptic Liturgy of St Gregory the Theologian

The liturgy is named after Gregory of Nazianzus, to whom Coptic tradition ascribes it^[2]; Wikipedia says that he wrote its core "cannot be excluded" but authorship is not established^[1]. Wikipedia says it derives from the West Syriac rite and was imported into Egypt after the 6th century by Syriac monks in Wadi El Natrun; its oldest manuscripts are an incomplete 10th-century Sahidic one from the White Monastery and 12th–13th-century Bohairic ones from the Monastery of St Macarius, and Patriarch Gabriel II's 12th-century canons permitted its use^[1]. The traditional Gregorian attribution and the Syriac origin Wikipedia describes do not sit easily together; this was not resolved here.

It is used on feasts, especially Nativity, Epiphany and Resurrection, and is addressed to the Son^[2]. Its Prayer of Reconciliation is the one addressed to the Son, after the prayer of the veil and before the anaphora^[2]. Neither source gives the prayer's text, so the incipit «أيها الكائن» quoted on the site was not verified.
