I know I always play the role of the defender of Atheists... (lol
)...but in this case, I perfectly understand his reaction.
He didn't mean to offend the Christians' religious sentiment. He was that emotional because he is very often asked why he has become an Atheist, despite his Anglican background.
And since he is supppsed to justify himself, he went wild for an instant.
Back to the topic...he kinda has a point.
Because the necessity of the sacrifice is not in the Gospels. It is a late elaboration by Augustine of Hippo.
What I mean: Augustine misinterpreted the sacrifice, which has a deeper theological meaning.
Jesus fell victim of the men' s brutality. Which represented the sins of the world. By falling victim, he forgave the sins of the world as victim (
hostia).
Ans sins are never a necessity. Sins are often the result of free will. And of chance, of course.
