yes, i do find it ironic (given what the Lord is really saying) that the ‘church’ of satan attacks both ethnic and religious jews by calling them the ‘synagogue’ of satan.
The descendants of Abraham were pointed towards the coming of The Messiah. The fact that they could look him in the face and deny him, means they were full of the enemy, and serve him only. Already, the Sadduccees and Pharisees were worshipping the process of sacrifices, and myriads of laws. The Torah is simple, it is easy to follow by the law, but the Spirit is missing in them. They condemn themselves by refusing the Gift they profess to wait for.
