Christ is both Not-created AND created.
Using methods of sensus plenior:
Jesus is the light
Jn 1:4 In him was life; and the life was the light of men. 5 ¶ And
the light shineth in darkness; and the darkness comprehended it not.
Jn 3:19 And this is the condemnation, that light is come into the

Since Holiness expresses a separateness, and the Godhead was unified in Love, Holiness waited for creation to be expressed. Immediately after the heavens and the earth were created God declared, "Let there be Light" and His holiness was made manifest.
Therefore we can say that Christ was created, that he is the firstfruits of creation  without fear of treading on his divinity.
He is both the Creator and a created man. That is the essence of incarnation.
 1Co 15:23 But every man in his own order: Christ the firstfruits; afterward they that are Christ’s at his coming.
