Eternal sin

Nathaniel William Taylor
At the heart of this objection is Taylor's view of the atonement. Many Christians believe that Christ's death upon the cross was as a sin-substitute, whereby the sins of mankind were imputed to Christ, who was punished for our sins in our place. Martin Luther went as far as to say that Christ became the worse sinner in the universe. Christ's righteousness, or his perfection, was then imputed to all believers. Consequently, God no longer sees believers as they really are but is blinded by imputed righteousness. For many Christians, this belief is the cornerstone of the Christian faith. Yet Taylor explicitly denied this view.
