i dont know help
The beginning of Christianity was in Israel at Pentecost when the Holy Spirit came on the disciples to form the Catholic Church.
Society for the Study of Early Christianity was created in 1987.
As far as I know, The true early christians never taught Reincarnation. As you probably well know, Christianity came from Judaism. Judaism never taught reincarnation. Reincarnation is primaraly a Pagan, that is either a religion that is not an abrahamic religion (Judaism, Christianity, Islam) or a religion that worships many gods, concept. Misguided early christians, may have incorporated reincarnation into their aldulturated form of Christianity. However, they were clearly not influential enough to influence mainstream Christianity. either that, or they saw the truth, in my opinion.
I think defined not redefined, because that was just the beginning of Christianity so Paul was defining what Christianity is.
Christianity has been infiltrated since its beginning almost 2000 years ago by false teachers. The only way to detect false teaching is to know the true teaching which comes from the Holy Bible.
Christianity is often considered as beginning at Pentecost, most likely in 33 AD.
Check out the book of Acts in the Bible.
Well, if you mean the start within the beliefs then the answer is in the beginning of time, if you mean the separation between Judaism and Christianity then the birth of Jesus in Bethlehem and the belief of him being the Messiah, if you mean the beginning of the followers this would be in Israel.
Jesus Jesus Christ was the beginning of Christianity. Paul tought Christianity after Christ and his appostles were killed off.
Christianity started with the teachings of Jesus Christ in the late 20s AD and early 30s AD.
