Do any church writers compare or contrast Jesus and the burning bush?

From the Wikipedia article on [Oneness Pentecostalism](http://en.m.wikipedia.org/wiki/Oneness_Pentecostalism) , >Oneness theology specifically maintains that God is absolutely and indivisibly one. It equally proclaims that God is not made of a physical body, but is an invisible spirit that can only be seen in theophanies (such as the burning bush) that he creates or manifests, or in the person of the incarnate Jesus Christ. In the person of Jesus, one sees the last, best, and complete theophany of God. Is there any existing church writings by church fathers, reformers, or Christian scholars pre-dating Oneness Pentecostalism that speak of a doctrine of Christ as a _theophany_, using as a comparison the burning bush or other manifestation of God's presence in a similar vein, either supporting or condemning the teaching?
