Nope, that is Deism. Christian TEs believe in the Christian God, who is intimately involved with his creation, united himself with it in the Incarnation, defeated sin and death, and rules the world as a resurrected human, Jesus the Christ.
There are obviously many metaphors and models that help Christians understand the atonement and different streams of Christianity prefer some over others. All streams of Christianity believe that Jesus’ death and resurrection atone for sin and make possible a right relationship with God.
All streams of orthodox Christianity affirm some basic creed that claims Christ has died, Christ is risen, Christ will come again.
What is God’s purpose in creating the New Creation? I would say completing the work he began at Creation and reconciling all things to himself under the just, righteous, and peaceful rule of his Son, Jesus.
Why would you say something like this?
Just because most people are some flavor of Protestants doesn’t mean we all reject the brotherhood and sisterhood of Roman Catholics in the Christian faith. Or Orthodox or Pentecostals. There are some Catholics and Orthodox around, don’t lump entire Christian faith traditions together under some pejorative label, please.
