Reform Judaism has now surpassed its 200th anniversary. Looking back, I believe it is possible to identify three stages through which our Movement has evolved and to see the beginnings of a fourth.
The essential difference between Jews and Christians is that Christians accept Jesus as messiah and personal savior. Jesus is not part of Jewish theology. Amongst Jews, Jesus is not considered a divine being. Therefore all holidays that have a connection to the life of Jesus are not part of Jewish life and/or practice (Christmas, Easter, Lent, Advent, Palm Sunday, etc.).
