This will come as a shock to most people to learn that New Testament scholarship is broadly in agreement that the gospels of Matthew and Luke do not portray Jesus as preexistent and have no awareness of the notion of the Incarnation of God. In the light of Christian teaching about the origins of Jesus this is surprising as both gospels have extended birth narratives where such ideas would naturally be mentioned. Here is an extract from a recent academic discussion from Yale University in the USA
