Sorry, but the Jews may have delivered Christ to the Romans for crucifixion, but they are not "responsible". God sacrificed his own son. They did not take his life, he laid it down. Hence no man is responsible for that crime. It was God's plan and God executed that plan perfectly in accordance with his will. And when it was all done, Christ asked his father to forgive them "for they know not what they do."
So you are saying that Peter got it wrong and you got it right? "Men of Israel ... you denied the Holy One and the Just, ... and killed the Prince of life ...". Perhaps he didn't finesse the words quite right so as to not "offend" his Jewish listeners? What he really meant to say ... .
Does that make you spiritually superior to Peter?
Sorry, Marlowe. Unlike you, the Jews heard Peter words, understood the implications (that unless they repented and turned from their culpability in killing Messiah they would be eternally lost), and believed Peter's message by turning to the Messiah. They proved by their repentance to be among God's elect remnant of Israel, and were saved from the wrath to come. They transfered their allegiance from the decaying old kingdom to the new kingdom of Christ built on His apostles and prophets.
You are in denial of these things because they do not fit into your nice, neat theology. You would rather have God punish millions for no reason, rather than acknowledge the linkage in Scripture between actions and consequences.
""Now it shall come to pass, if you diligently obey the voice of the Lord your God, to observe carefully all His commandments which I command you today, that the Lord your God will set you high above all nations of the earth. And all these blessings shall come upon you and overtake you, because you obey the voice of the Lord your God: ... But it shall come to pass, if you do not obey the voice of the Lord your God, to observe carefully all His commandments and His statutes which I command you today, that all these curses will come upon you and overtake you:" (Deut. 28:1,2,15).
