"The earliest days of the faith" would be the ~40 years before the gospels were written, not third century councils.
Christians can't have collectively rejected Arianism if there were Arian Christians, several kingdoms even to be uprooted by Rome. The fact that there were Arians to reject is itself proof that there was no unanimity.
