l am not a Christian, so l don't believe Gospels to be historically reliable nor theologically reliable, l merely use Gospels, because this is what you would be most familiar with.

My premise is that Quran is not wrong about Jews boasting over death of Jesus, because we can demonstrate Jews attempting to get Jesus killed from Gospels, that you are more familiar with.

In Islam, we have our own reasons and our own understanding of death of Jesus but you are not familiar with our thinking, so l used Gospels -

However, l can explain how we understand death of Jesus, or why we reject his death and why this event happened from Islamic perspective, if you are interested.
