Via Rorate comes this video of a Hierarchical Divine Liturgy (Pontifical Mass) for the Solemn Feast of the Nativity of the Lord. This Liturgy was served by Bishop Milan Šašik, Eparch of Mukachevo, in the Ruthenian-Greek Rite. This was only last week as Dec. 25th on the Julian Calendar (used by many Eastern Rites) coincides with Jan 7th on the Gregorian Calendar.
I present this for two reasons. First there is the liturgical eye candy of a Hierarchical Divine Liturgy in Church Slavonic (the liturgical and historical equivalent of Latin in Slavic lands), which is every bit as awe-inspiring and beautiful as a Latin Rite Pontifical High Mass. Second, the Latin Rite con-celebrant is Archbishop Thomas Edward Gullickson, Apostolic Nuncio to Ukraine, who himself is a blogger and ardent supporter of the Traditional Latin Rite and has called out his brother-bishops for not promoting it, back when he was stationed in the Caribbean.
