I hope to catch this tonight, as I've never seen it before
Before watching it, read through the information at the link posted above, regarding this liturgy. It will make more sense. Keep in mind, too, that this Mass was celebrated in the 'vernacular' of the Maronite homeland, Lebanon, i.e. Arabic. Portions of the liturgy retain their original Syriac and Aramaic, especially the Words of Institution chanted by the Patriarch, using the language and words of our Lord at the Last Supper. This is true in the US, as well, where the 'vernacular' is English but the other portions of the liturgy are in Syriac and Aramaic.
You're in for a very ancient and reverent liturgy. Enjoy!
