@VooDooMedic I'll argue that it began in Ezekiel 10, the moment God's glory left the temple (because they had already stopped following God in their hearts and deeds, and twisted the Law into their own version of it) and was no longer literally visible to them, but they kept following tradition anyway.

The god of the Jews did not "abandon" them and neither did he die to be their final sacrifice at the cross. So it's definitely not the same God as Christianity's anymore.
