Fair enough: I don’t like hit and run posts. But your comment, itself, was pretty much a hit an run.
I apologize if that’s how it came across. It certainly was not intended to be like that.
If you reduce the liturgy to essential form: scrpture readings, homily, anaphora, communion, then yes the EO liturgy is litle changed over the past 1700 years. But that is also true even for the Latin Novos Ordo.
I’m not quite sure I follow. The
Novus Ordo Missae is a tricky creature, since that was created in the last 50 or so years. Certainly not completely from scratch, but I don’t see how it has not changed in the past 1700 years when it is only 50 years or so old. Are you saying that the
Novus Ordo Missae has the same basic components that the Divine Liturgy of St. John Chrysostom does? If so, then you’ll get no argument from me there. I completely agree with that.
On the other hand if you are talking about texts used in liturgical prayers and hymns, and in particular the non-scriptual texts, then what you celebrated today has only very little in common with that which was celebrated 1700 years ago.
Well, in that sense I can see the argument. But then in turn, you would have to say the same from the Tridentine Mass as well as the
Novus Ordo Missae. Aren’t they called “propers” in the West?
You might consider each of the hymns - antiphons, risagion, cherubikon, creed, axion estin etc. and find out when they were introduced. You might like to consider how the replacement of the syriac rite with byzantine rite and what changed the liturgy. There is no shortage ofliterature on these subjects.
Wouldn’t the Syriac Rite situation only be an issue for the Antiochians? I admit I am not as well versed on the subject of liturgical conformity vis-a-vis the Antiochians, but I am familiar with it a little bit in regards to the Maronites. I would venture to say that it was not too drastic of a change for the Antiochians to adopt the Byzantine Rite. Have you been to a Syriac Orthodox liturgy? It is extremely similar to the DL of St. John. My former Maronite priest told me that he went with a Melkite priest one time to a Syriac Orthodox liturgy. The Melkite priest turned to him and said “I am glad we adopted the Byzantine Rite. They sound like they’re calling for sheep!”

I will say that I do not consider one superior to another though. Syriac chanting has a unique aesthetic feel to it.
From what I have read and understand, St. John Chrysostom took the liturgy that had been in use for perhaps centuries and shortened it. Apparently, the liturgy before that was 6 hours long!

But I don’t think the additions of various hymns constitutes a change to the corpus of the liturgy. I always thought of them as synonymous to the Propers in the West. Would this be a correct analogy?
