Christ was a Jew and honored the feasts, etc. He was speaking of a 'faction' who 'call themselves Jews'. Operative words are 'call themselves'.

The ones you are speaking of are those such as the Roths, etc. who 'call themselves Jews'. It is based on of the oldest deception ever perpetrated on humanity and it began with 'you can be like God'.

Blessings to you and all you love. May His hand 'BE' upon us all and may He bless us with added measures of Wisdom and Discernment in these wicked days.

Lamentations 4:7
7 Her Nazarites were purer than snow, they were whiter than milk, they were more ruddy in body than rubies, their polishing was of sapphire:

Jesus WAS NOT A JEW
