If you look at historical records orthodoxy has not been the standard since the beginning. Certainly in Temple days there were a lot of different ways to be a Jew. Think pharisees, sadducees, ascetics who renounced sexual relations, etc. The idea of uniformity the orthodox insist on is a relatively recent heresy.
