Cyprian

That it is impossible to attain to God the Father, except by His Son Jesus Christ:

In the Gospel: "I am the way, and the truth, and the life: no one cometh to the Father but by me." ...Also to the Romans: "For all have sinned, and fail of the glory of God; but they are justified by His gift and grace, through the redemption which is in Christ Jesus." Also in the Epistle of Peter the apostle: "Christ hath died once for our sins, the just for the unjust, that He might present us to God."
