One baffling aspect of the mediaeval Ethiopic version of Traditio apostolica is the presence of an additional baptismal rite, apart from a version of that found in other versions of Traditio apostolica (ed. Hugo Duensing, Der Äthiopische Text der Kirchenordnung des Hippolyt (Göttingen: Vandenhoeck & Ruprecht, 1946), 81-127.)
Alessandro Bausi, “The baptismal ritual in the earliest Ethiopic canonical liturgical collection” in Heinzgerd Brakmann et al (ed), Neugeboren aus Wasser und Heiligem Geist”: Kölner Kolloquium zur Initiatio Christiana (Münster: Aschendorff, 2020), 31-83 has now published a version of a clearly closely related baptismal ritual from the Axumite collection from which he derived the new text of Traditio apostolica. I have yet to explore it in detail, but since I have at present, as a result of the ongoing discussion with Maxwell Johnson about the interrogation in the Egyptian rite, a particular interest in the introduction of the syntaxis into Egyptian baptismal rites (generally suggested to have taken place in the fourth century on the basis of the appearance of such a syntaxis in Canones Hippolyti, evidence which has now disappeared with the denial of an Egyptian provenance to this document) and in the role and presence of the five-membered creed found in the Deir Balizeh papyrus and elsewhere (including Epistula apostolorum) as part of my overall argument that declaratory creeds are no less primitive than interrogatory creeds (though the language is misleading), I took a particular interest in the baptismal confession found in the Axumite ordo.
Essentially this baptismal confession is the same as that found in the present Coptic rite, namely the declaration of the five-membered creed, followed by a brief interrogation: “Do you believe?” “I believe” repeated three times. What is notable, however, is the absence of any syntaxis. This implies a rather later entrée of the syntaxis into Egyptian rites (it is, for instance, present in the current Coptic rite) than previously thought.
Turning to the version in the mediaeval Ethiopic of Traditio apostolica we find that the same baptismal profession that is in the Axumite rite, as in the present Coptic rite, in in place, namely the prompted repetition of the five-membered creed and the repeated question “Do you believe?” (though are very slight variations between the Axumite version and the mediaeval version.) This later rite, however, has a syntaxis. This syntaxis, however, is none other than, yet again, the same five-membered creed, which is thus repeated twice in the ritual! In the version of the rite of Traditio apostolica within this text the same, expanded, version of the five-membered creed as found in the Coptic version of the Traditio is found, albeit partly conformed to the interrogatory shape of the original. But given that the version in the second ritual lacks the expansions this can hardly be put down to the influence of Traditio apostolica. I think there may be more to say about this… but consider that after writing a 138 word sentence that that’s enough for now.
