Trans-Carpatho Rusyn (Ruthenian) --my father's people

I came across this on Rorate Caeli.   My father discovered his parents were not Russian Orthodox as he had believed until his 40s, but Trans-Carpatho Rusyn or Ruthenian---and thus Byzantine Catholics, who had been Catholics for 300 years. This sure sounds like the Russian Orthodox services I attended from time to time as a child. (Here's the link:  http://rorate-caeli.blogspot.com/2012/01/greek-catholic-christmas-hierarchical.html)

Hierarchical Divine Liturgy of Christmas (according to the Julian Calendar, or January 7 according to the Gregorian Calendar) offered by Bishop Milan Šašik, C.M., the Carpatho-Rusyn (Ruthenian) Greek Catholic Bishop of Mukachevo. The Latin-Rite prelate concelebrating with him is the Apostolic Nuncio to Ukraine, Archbishop Thomas Edward Gullickson, a blogging bishop known for his Tradition-friendly views and a reader of Rorate Caeli. (H/t to a reader.)
The complete video of Bishop Milan Šašik's enthronement was posted on Rorate last year.
