What do these phrases mean? Is this Latin?

Question

Just these two phrases

"Donum Crentum Dei"

"Opus Aurei"

Answer 1

"the bloodthirsty gift of God"

"the work of the golden one"

"the wizard of ruin"

"He [or possibly she or it] has slaughtered your sad [something--"sorrow" would be "tuam maestitiam"]      , the bloodthirsty gift of God; he will devour your pride, eternal servitude: the bloodthirsty gift of God."  In the second part of this sentence, "eternal servitude" is in the nominative case and thus should be the subject, but in the first part, there's no stated subject, unless "the bloodthirsty gift of God" is the subject of both verbs--in which case there's no role for "eternal servitude."

Answer 2

The blood gift of God.

A work of gold.

The sorcerer of ruin.

The blood gift of God killed your grief; the eternal Servant will take away your mourning: the blood gift of God.
