Firestar. Be careful dude. I am certainly not a religious 'freak' as you so eloquently call them, but I think I would get my facts straight if I were you, before you post something completely random on the Net and embarrass urself! Where did Jesus ever sin. Pray-tell?
As far as the meaning of the song. I don't think he's speaking to Christians at all. I think he's generally saying take the thorn out of ur eye before you judge me.
I agree with Raichu & Jonathon. Besides, he's saying 'you're no Jesus' connoting that Jesus is perfect, and no one else is. Geez, its not that difficult! Even Seether admits it!
Firestar. Take heed of these lyrics urself perhaps. Before you put all Christians in the same pot, eh?
