Paul says in 1 Tessalonians 2:14-16
"...from the Jews, who killed the Lord Jesus and the prophets and also drove us out. They displease God and are hostile to all men...The wrath of God has come upon them at last."
Needless to say, these verses are almost never quoted at Christian gatherings. More importantly, the Gospels are only a portion of the New Testament, so saying that the Gospels are not anti-semitic is like saying that in the OT only Genesis is really true.
The various rationalizations that "we all killed Jesus," or that "Romans killed Jesus," or that "only Jewish high priests have blood on their hands" etc. are in disagreement with Paul's own words blaming "the Jews" for the death of "Lord Jesus and the prophets."
It doesn't matter who killed Jesus , because he gave his own life willing to die for our sins ....so we all shall be saved.
and he rose again on the 3rd day...
