Is not going to save you.
I'm pretty sure that's not what AE meant. He's generally a bit more nuanced in his thoughts about Christianity.
Also, since you do seem to believe that there is an unforgiveable sin, does that mean that Jesus' death wasn't great enough to cover everything? Doesn't that seem a bit blasphemous in itself: Oh, sorry Son of God, you just endured an extremely gruesome death and defeated the forces of Satan, but it just doesn't quite cover it when someone decides to do something particularly nasty.
Paul warned the church many times saying if you stayed in sin that you would die, so if you commit sin after you ask for repentance it is mark onto you for death. The people who commit the unforgivable sin is so far from God that they don't recognized that they just committed that sin so therefore they will never repent of that sin.
