Rebecca,

The key here is:

"having BECOME so much better than the angels"

In other words, JC, in Clement's view, has achieved something he didn't already possess, just as in our Oral Torah sources tzaddikim are greater than angels due to their achievements than move them beyond the level of the "ordinary man" per Ps. 8:5.

No evidence of JC's "Deity" here, I'm afraid.
