Which Eastern Catholic liturgies today (if any) typically, or even occasionally, celebrate the liturgy versus populum? When did this start? 20th c.? 21st c.? I’m assuming that the majority of Eastern Catholics still worship ad orientem?
If I may, I’ll add a few things to what [post=11373311]shlomo3amrooh[/post] has already said.
The Maronites in the US jumped in the versus populum table bandwagon in the late 1960s, and this is perhaps the first, and most obvious, of the Novus Ordo-inspired neo-latinizations to have infected out Church. It has been standard in this country ever since, but there have ever been a small handful of exceptions. The trend took hold later – and more gradually – in the Patriarchal territories and elsewhere in the diaspora, but again, it has, most unfortunately, become the norm. IOW, for the Maronites, the correct ad orientem posture remains the exception.
IIRC, the SCC started this versus populum table silliness rather later, that being sometime in the mid to late 1980s. Here again, while it’s not ubiquitous it has unfortunately become more and more the norm. From what I understand, this is also true of the Copts and the Ethiopians. I’ve heard the same about the Armenians, but I’ve no experience with that, even by way of video or broadcast.
The Chaldeans seem to be more of a mixed bag, since most went (and remain) versus populum but some held fast to ad orientem or have returned to it. And not only in the western US. For example, I believe that the Mar Youhannan Zora in Canada has retained or reverted to the proper ad orientem posture.
The Syro-Malabars are an interesting case, though: in the immediate post-conciliar era, they too, mostly jumped on the versus populum bandwagon, although I believe at least the Archdiocese of Chanangassery did not. Lately, though under the guidance of Mar George Allenchery, himself from Chanangassery, they seem to be steadily reverting to ad orientem.
Although the Melkites are known to use versus populum (and forgo even a portable iconostasis) at times and in some places, they mostly retain ad orientem. The latter is true for the Byzantines in general.
