Luther

He sacrifices Himself on the cross, becomes a sinner and a curse; and yet He alone is the blessed seed through whom all the world shall be blessed, that is, redeemed from sin and death. And that He hangs on the cross between two malefactors, being counted equal to them, and that He dies there a shameful death, all this He does for the benefit of the whole human race, to redeem it from the eternal curse. Thus He is both the greatest and the only sinner on earth, for He bears all the world’s sin, and the only righteous and holy One; for no man can be made righteous and holy before God save through Him alone.—Sermon, 1540.
