@Samkelly,
I can tell you what the words mean, but I'm having a hard time linking
them together grammatically.
Magnum -- great
ipsum -- itself
deificum -- deifying, making god-like
Ipsum -- itself
glorifica -- glorify (as a command)
Opus -- work (the noun)
dominus -- lord
Sanctus -- holy
Are you sure about the spelling?
Word endings make a big difference in Latin.
