I have been listening to a pastor called Jim Staley, info link below
He is, I suppose a sort of messianic Jew but he's not a Jew but he and his family now follow and celebrate the Jewish calender / holidays.
He was speaking to a Jewish client /friend who told him the biggest reason Jews felt unable to take christians seriously was because ( apart from not believing Jesus was the one ) that they followed who they believed to be the Jewish Messiah but then went and changed all the feast days etc.
Is there any biblical back up for the church changing these things and then putting most of our festival dates on top of pagan holidays?
What thoughts on this.
I haven't explained myself very well hope you all understand what I'm on about.
