He is a deist.
What is the source for his deity?
The doctrine of Deism says deity created the worlds, set laws in motion, but does not involve himself in the affairs of mankind. Deism rejects all Revelation and miracles. In other words, Deism says the deity is not seen in reality. The absence of deity in reality corresponds to Atheism, which says the same.
The Biblical Theos is involved with reality from cover to cover.
Deism has one motive: to evade the eternal existence of matter. Atheism believes matter has had eternal existence because no deity exists to have caused its existence.
