This is a reconstruction of a sabbath liturgy for the Tefillah of the Amidah, at least in some variant of its public recitation, in Greek and preserved in an early Christian work, the Constitutiones Apostolorum (Apostolic Constitutions), a Christian work compiled around 380 CE in Syria. Several prayers derived from Jewish sources appear in the Apostolic Constitutions and they can be found grouped together and labeled “Greek” or “Hellenistic Syanagogal Works” in collections of apocrypha and pseudepigrapha. Because explicitly Christian references appeared to be added onto a pre-existing text with familiar Jewish or “Old Testament” themes and references, scholars in the late 19th century were already suggesting that as many as 16 of the prayers in the Apostolic Constitutions books 7 and 8 were derived from Jewish prayers. A more modern appraisal was made by Dr. Fiensy and published in Prayers Alleged to Be Jewish (Scholars Press 1985). Based on a careful analysis of the prayers, he concludes that the only prayers which can be identified as Jewish with certainty are those found in sections 33-38 of book 7.
