Don't know about the liturgy celebrated in 1957. I have been attending the Maronite Catholic Church for more than a decade. It is my understanding that all of the Eastern Catholic Churches benefited from VCII in that they were told to restore their ancient liturgies. In 2004, the Patriarch convened a synod. Among the issues discussed was the expansion of the church around the globe and the need to standardize and translate the liturgy, beginning with the most common: English, French, Spanish and Arabic. (Up until then, each eparchy had translated the liturgy into the local vernacular. As such, the English format differed in the US, Canada, Australia, So. Africa, Britain, etc.) Last year, the new English missals were issued and delivered to all English language countries. The English format of various hymns, was also standardized.
Hope this is helpful.
That's certainly an outcome of VII I hadn't previously been privy to!
Thanks for the info. No gas money for this weekend or I might attend also.
