What would have been lost if Caedmon simply repeated the name God

2- What would have been lost if Caedmon, instead of using a variety of expressions for God, had simply repeated the name God?

Now we must praise . . . God,

God’s might . . . and his mind plans,

the work of God, . . . when he of wonders every one,

God, . . . the beginning established.

He first created . . . for men’s sons

heaven as a roof, . . . God;

then middle-earth . . . God,

God, . . . afterwards made–

for men earth, . . . God.
