Sorry, dude, but that's bad theology.
It does not compute. Or, in other words, you're missing the point.
The book you're quoting was made AFTER the Christ died for our sins, so obviously it is going to make his sacrifice for our sins the key point. But if you take the sacrifice out... The equation changes, doesn't it? As a result your quotations are proof of nothing, because we're talking about the alternate reality. The one where Christ did not die for out sins and punished those who tried to kill him instead. If anything in this world YOU are considered a heretic, because the Lord surely couldn't have been so weak as to let himself be killed by the unbelievers.
