The issue isn't whether commentators "today" think Jesus is a God, but rather if the writers of The New Testament thought Jesus was a God. McGrath, Kirk, and I say the writers of The New Testament didn't think Jesus was a God, but rather a human person.
At the time of Jesus you had many branches of Jewish religion, Jesus was said to have been a Nazarene. Was Jesus Jewish in religion? At the Council of Jamnia, the Jews said, no - his religion was not Jewish. So what was Jesus? It seems he was Gnostic in thinking. This shows up with Jesus’s followers that went north being Christians and the ones that stay in Israel and Egypt being Gnostic.
We can see how the Christians thought about the question man/god back around the year 200. Here is data from Wikipedia. The Church being out of Rome.
The distinction between the human and divine Saviour was a major point of contention between the Valentinians and the Church. Valentinus separated Christ into three figures; the spiritual, the psychical and material. Each of the three Christ figures had its own meaning and purpose. They acknowledged that Christ suffered and died, but believed that “in his incarnation, Christ transcended human nature so that he could prevail over death by divine power". These beliefs are what caused Irenaeus to say of the Valentinians, “Certainly they confess with their tongues the one Jesus Christ, but in their minds they divide him.
Then a few decades latter we had Arian.
Arianism is a Christian belief that asserts that Jesus Christ is the Son of God who was created by God the Father at a point in time, is distinct from the Father and is therefore subordinate to the Father. Arian teachings were first attributed to Arius (c. AD 250–336), a Christian presbyter in Alexandria, Egypt.
So, yea, I see your point and would agree that the god thinking came latter.
