OK,
Here is what I say to my friends and family that complain that the "Jews killed Jesus": That was preordained and part of God's plan, if we claim to be Christian, we cannot say God was wrong when he planned the very thing that is the bedrock of the Christian Faith. Without the Resurrection, there would be no Christians, and without the "Passion" and Jesus asking God to "forgive them, they know not what they do"; there would be no Resurrection. If it had not happened we would still be Jews also.
