New Testament Biblical Theology Class Last Night

Last night in my NT Biblical Theology class the question was posed about Paul's reaction to today's statistic that 60% of Christians believe that Jesus sinned while he was on earth as a result of today's church leaders not teaching the biblical truth. So if that is true, 60% of Christians believe that Jesus did, in fact, sin, I wonder if they have eternal salvation.

Lets look at the facts:

1. All through the OT, God's people looked forward to the perfect sacrifice (Jesus) to free them from sin. In looking forward to that, they sacrificed spotless lambs
2. The bible says, Jesus was the perfect sacrifice, not giving into temptation and living a sinless life.
3. If Jesus did sin, then how is his death different than mine?

I'm sure there are other truths to look at but if we just take these three, can that 60% still be saved if they believe that, even tho Jesus sinned, he still died for the sin of the world. Is that possible?

Comments welcome.
