The Jєωιѕн nation is responsible for the Crucifixion. Their leaders had him seized, handed him over to Pilate, and demanded his death.
Collective responsibility doesn't mean that every Jєω today is shouting "crucify him." What it means is that the Jєωιѕн nation and religion, as a whole, carried out the deed and they have waged war against the Church ever since.
If you think of the Germans, they are held collectively responsible for World War II, but certainly the individual German was not directly involved in that decision, nevertheless he supported his nation. Now, the Germans today have disassociated themselves from National Socialism, but the fact remains they are held accountable, (unjustly, I might add) even though they have repudiated the acts of that state.
The Jєωs and the Jєωιѕн religion have not repudiated the Crucifixion. They remain at war with Christianity.
The Jєωιѕн nation brought about the Crucifixion of Christ. Does that mean the Jєωs cannot be saved or redeemed? Of course not. It does mean, that so long as they do not repudiate what their nation did and accept the Gospel, they remain loyal to those who brought about the Crucifixion.
