What is a Judeo-Christian culture?
The Jews do not accept Jesus as Messiah!
Christians also view him as the Messiah foretold in the Old Testament; however, Judaism rejects these claims. Islam considers Jesus a prophet and also the Messiah while several other religions revere him in some way.
What World-famous Men have said About the Jews and above statements clearly demonstrate that the Jews conspired to murder Jesus at Jerusalem and later his brother James at Rome. On the other hand the Muslims respect Jesus and his mother Merry.
Therefore dreaming and falsely engineering a romantic relation between the Jews and Christians does not stand. So is the notion of Judeo-Christian culture.
