I can’t tell you much about this, but I could at least translate the YouTube note to know that this is a Hungarian Baptist church.
Liszt: O salutaris hostia
La Caffettiera Stioppeta, directed by Eszter Murányi
O salutaris Hostia,
Quae caeli pandis ostium:
Bella premunt hostilia,
Da robur, fer auxilium.
[Uni trinoque Domino
Sit sempiterna gloria,
Qui vitam sine termino
Nobis donet in patria.]
Amen.
O saving Victim, opening wide
The gate of Heaven to us below;
Our foes press hard on every side;
Your aid supply; Your strength bestow.
[To your great name be endless praise,
Immortal Godhead, One in Three.
O grant us endless length of days,
In our true native land with thee.]
Amen.
