but i think it all started with the birth of "Jesus."
We were talking about the Roman Catholic Church.
Christianity began in the area of the Jordan where John the Baptist was preaching, when people started listening to John and following Christ. Jesus
was about 27 or 28 at the time He began His ministry. The earliest Christians were messianic Jews. It was some years after Calvary before these
believing Jews started breaking down their prejudice against Gentiles and witnessing to them. It spread west to Rome many years after the birth of
Christ.
Yet some, such as I believe that there was only one true religion from the very start- from Genesis on, the center of which was Christ the Messiah.
The way of salvation never changed, only the teaching methods God used. We believe that most of the appearances of God or the Angel of the Lord were
actually Jesus in a pre-incarnate form.
