Well seeing that Jesus was God manifest in the flesh (as a Jew), and that HE came expressively to give HIS life a ransom for many. 'Looking onto Jesus, the author and finisher of our faith, who for the joy that was set before HIM, endured the cross, despising the shame, and is set down at the right hand of God...'
Given all that... 'Jew as Christ-killer' isn't going to stick...Without the Redeemer washing us in HIS precious blood -- we'd all be lost...
