Evolutionary interpretations of the history of religion are usually understood to be an explanation of the phenomenon of religion as a result of a contuinuous development. The model for such development is the growth of living beings which leads to increasingly subtle differentiation and integration. Within such a framework of thought, monotheism would be interpreted as the result of a continuous development from animism, polytheism, henotheism and monolatry to belief in the one and only God. Such a development cannot be proved. Monotheism appeared suddenly, though not without being prepared for.
Christians were seen as polytheists, due to the doctrine of the Trinity. In the last few hundred years, rabbis have moderated this view slightly, but they still do not regard Christians as being fully monotheistic in the same manner as Jews or Muslims. Muslims were acknowledged as monotheists.
It is the Islamic belief that Christianity is not monotheistic, as it claims, but rather polytheistic with the trinity-the father, son and the Holy Ghost.
