Most Christians know very little about their church history. They have no idea about the wide variety of beliefs of the early Christian. (I don't know if you could call them "christians"). Most people have no idea about the history and development of the multitude of biblical canons or the forging of orthodox Christian theology.
The church was a hoax since the beginning.
Think about it, Jesus was not important historically, as he was not mentioned by any contemporary historians, Jewish, Roman, Greek, or otherwise. I think that if the guy ever existed, (yeah, right), he was a Rabbi who was crucified by Rome (at most). The supernatural deeds recorded in the bible are merely legend.
Ebionites were very Jewish Christians.
They believed in 1 god, but, they believed Jesus was completely human and not divine. They also believe Paul was an arch heretic. http://ebionite.org/ – Claim to be modern Ebionites.
Marcionites were Gentiles who claimed Jewish practice was harmful for a relationship with god.
They were followers or Marcion, a real person in the 2nd century. They believed in two gods, one Jewish and one Christian. They believed Jesus was completely divine and not human. They believed Paul was the one true apostle of Christ. (Here you have a huge contradiction. One claimed Paul was an apostle and the other group claimed, Paul is an SOB).
Now here is another problem. Marcion (a real person considered a heretic by Proto-Orthodox Christianity) created the 1st Christian NT Canon around 144 CE. It contained a version of the gospel of Luke and 10 of the 13 letters of Paul, namely Romans, 1st & 2nd Corinthians, Galatians, Ephesians, Philippians, Colossians, 1st & 2nd Thessalonians, and Philemon.
What should we do? Should we discard those gospels?
Gnostics
Very spiritual and many widely varying subsets.
Believed Jesus was a spirit and did not suffer, but only appeared to suffer.
They believed in salvation through mysterious knowledge.
This world is full of ignorance and suffering; salvation comes not by making it better but by escaping it.
The described "congregations/churches", where the ones closet to the "event", and they can't even get their shit strait. Do some research.
