What is your point or your objective in repeatedly claiming on this Forum that Christianity is actually Judaism? Are you a Biblical scholar trained in Hebrew and Greek who examined primary sources? What yeshiva or seminary did you graduate from? Are your theories published, so that other scholars can comment on your theory?
The Bible, and the fact that the Apostles never stoped being Jewish. The orginal controversy was wether Gentiles could be saved without becoming Jews. This was Acts 15.
