You misunderstood. Phil 2:5-8 explicitly states Jesus "did not count equality with God a thing to be grasped." Adam was disobedient because he aspired to be godlike; unlike Adam, Jesus was obedient "unto death, even death on a cross." This is the Pauline theology of the First and Second Adam, which St. Paul appears to have inherited from his predecessors in the Jesus movement.

The issue here isn't what you or I or the Church in the fourth century thought about Jesus, or even what Jesus himself thought about his identity. It concerns what the earliest Christians thought about Jesus.

Your last paragraph is way off the mark. Many, probably a plurality of, New Testament scholars are also Christians.
