The hymns generally known under the title Te Deum have played a major role in the liturgy of the western tradition of Christian worship. The Te Deum hymns have been in use since quite early in the development of a distinct western liturgy, but their origin may not be in the West. In the present article, Anton Baumstark compares the text of the Te Deum hymns to the texts of early Greek Eucharistic prayers and finds several noteworthy correlations. Baumstark provides segments of the Latin and Greek texts of the hymns and prayers in parallel columns and then discusses the features that they have in common. Baumstark also provides comparisons with the traditions of Eucharistic prayers in other Eastern traditions, namely the Syriac and Arabic traditions.
