Newly uploaded to academia.edu is a forthcoming article in Questions liturgiques in which I build on previous work which suggested that the syntaxis was the earliest form of baptismal confession in Syria, by suggesting that Alexandria also had some form of creedal declaration as part of the baptismal rite from the earliest times.
This means that the common assertion, largely based on the baptismal rite of Traditio apostolica, that the earliest form of baptismal creed was interrogatory, and thus that any creedal declaration is of necessity later, falls apart. I suggest that the so-called “interrogatory” creeds are all western, and thus that Traditio apostolica reflects a western rite.
There’s more, but you can read it for yourselves!
Once again, naïve use of the church order material has proved misleading.
