I think if we ask the question,
"Why did Jesus die?"
most would say,
"He died for our sins
and
He saved us from the consequences of our sins,"
In fact,
there's only one very brief reference in the Gospel accounts
of the death of Jesus
that would indicate that He died for our sins.
Only in Matthew's Gospel,
when He changes the wine into His blood,
does He say, "This is the cup offered for the forgiveness of sins."
Otherwise, it is not so in the Scriptures.
Probably it would be a better question to ask,
Why was Jesus killed?
Why did they do this to Him?
Why did they hate Him so much
that they were ready to kill Him?
The answer seems to be that Jesus spoke such a radical message
and asked for such dramatic changes
that the hierarchy could not afford to let Him live
lest their positions of authority be threatened.
From outside of an institution
its critics are simply ignored;
but Prophets (from within an Institution)
have to be destroyed.
Rather than blaming us for Jesus’ death,
the hierarchists throughout history
and even today who destroy those who truly emulate Jesus
might just look in the mirror.
