As for the Latin lyrics of Lux Aurumque - which means Light and Gold - they are...
Pura velut aurum
canunt et canunt et canunt
... which means (according to this translator) ...
Pure as if gold
(They) sing/prophesy and (they) sing/prophesy and (they) sing/prophesy.
*'Gravis que' is actually written and said as one word, Gravisque, meaning "and [definition]. There are so many words listed because it actually means all of those, in a poetic sense that is difficult to capture in one word in English.
It is an English poem by Edward Esch, translated into Latin by Charles Anthony Silvestri. English: "Light,
Warm and heavy as pure gold and the angels sing softly to the newborn baby."
