The problem here is folks who want to cast it as some thing not foreshadowed from the word “go” in Holy Writ. Older strains of rabbinical thought were receptive to the idea of a Messiah who would do things like the New Testament attributes to Jesus.
In fact the New Testament is quite bold and says that Christ was in the cloud that Moses and the Hebrew people followed.
History’s four schisms that plague the Roman Catholic Church:
The reign and later betrayal of Charlemagne
The Prostestant Reformation led by Martin Luther
The reign of two Popes, one from Italy and one from Spain
The adoption of the American Constitution.
