متن اصلی - لاتین - Miseribus, Sanctus...

Is this pseudo Latin again?

I thought so to. But using the books again 'Miseremos' can be written with o insted of u.

Domine deo Sabaoth is also another variety.
I accepted it as Latin and translated it.

Well, it is some darkness cult band but they have managed to make it up correctly. (And once again showed that my "old style Latin" is useful)
