Right. But by the 17th century Judaism was pretty much non-existent. For all intents and purposes in the Western world, it was an anachronism that would have existed outside its proper time and place in salvation history.
And Pilate seeing that he prevailed nothing, but that rather a tumult was made, taking water washed his hands before the people, saying: I am innocent of the blood of this just man. Look you to it. And the whole people answering, said: His blood be upon us and upon our children. Then he released to them Barabbas: and having scourged Jesus, delivered him unto them to be crucified. (Matthew 27:24-26)
STOP blaming the Jews who did only what God fore ordained them to do... MY sins put the Savior of all creation, on that cross. That is not theoretical it is historical, biblical fact.
If Jan had been taught that in the doctrines of his faith... he would have defended Jews at the proper time. At that time, the Church did NOT allow most Christians to see the actual Scriptures in toto... as the Church was then THE Geo political force in the world. But this is OUR time. Our Nation need not fight FOR the Israeli's. We need to keep our national imperative on LETTING and KEEPING them off the chain.
