AnswerScholars are uncertain as to the earliest Christian sects, but they seem to have included several Gnostic sects, of which the Cainites, Sethians, Ophites may be among the earliest. Another early Christian sect was the Nazarenes, sometimes associated with the Jerusalem Church of which Paul said James and Peter seemed to be pillars. The Nazarenes appear to have been split into two distinct groups. the Nazarenes and Ebionites. Edward Gibbon estimated that around fifty early Christian sects existed.

Many new denominations arose during the centuries that followed, but eventually disappeared or were suppressed by the dominant Christian Church.

Numerous Chistian denominations and independent churches exist today, some with only a few dozen or hundreds of followers.
