Max,

I would like to remind all the Jesus people quoting what he said that he
was born a Jew, Lived and preached the Jewish Faith (He was a Jewish
Rabbi) be died a Jew on the Cross and was resurrected a Jew. He never
ever ONCE preached or attended a Christian Church.

The first followers of Jesus were Jews, still followers of the Jewish
Faith. Their leader was his Brother.

I wonder if anyone can tell us when, how, and where the Christian Church
came into being?

This is a complex question. Clearly there were followers of Jesus
before the crucification. However, in those early days "Christianity"
was a Jewish sect and followed most the Jewish practices of the day.
The Gospels Matthew and Mark were clearly written to appeal to a
Jewish audience. Paul changed that, by creating communities that were
mainly Gentile, or formally "Pagan." So you could say that around 50
CE Christianity was a Jewish sect, but fifty years later most
Christians were probably not Jews.

One must keep in mind that that this was a very tiny group - It has
been estimated that there were less than 150 Christians in 100 CE.
Thus, its really difficult to say what the background of the majority
was at any time. To make it even harder to sort out, there were a
number of Christian sects, some mainly Jewish, some not, that did not
survive. The sect that led to "normative Christianity" was possibly a
minority in the early days. Following the Council of Nicea (325) the
dissenting sects were wiped out and their writing generally destroyed.

One must also keep in mind that there were certain political forces at
play. The Jews enjoyed a special status in the Roman Empire as an
"ancient religion." They were exempt from showing subservience to the
various local gods. If Christians were not Jews, they enjoyed no such
benefits. On the other hand, during the several Jewish revolts it
was not cool to be Jewish. You can find echoes of all of this in the
Gospels.

Curiously, this special status of the Jews was a significant factor.
Although they enjoyed a unique religious freedom, they were also
responsible to pay an extra tax to support the Temple in Jerusalem.
The major building program of Herod worsened this, and led to the
unrest that was prevalent in the time of Jesus.
