This letter was written by someone who simply referred to himself as a disciple of the apostles. He wrote this letter to a certain Diognetus some time in the second century AD. It is one of the documents in a collection referred to as the Apostolic Fathers, writings of leaders in the church the next generation after the time of the apostles. The full text of this letter may be found here. The citation below comes from chapter 9 of this letter.

But when our wickedness had reached its height, and it had been clearly shown that its reward, punishment and death, was impending over us; and when the time had come which God had before appointed for manifesting His own kindness and power, how the one love of God, through exceeding regard for men, did not regard us with hatred, nor thrust us away, nor remember our iniquity against us, but showed great long-suffering, and bore with us, He Himself took on Him the burden of our iniquities, He gave His own Son as a ransom for us, the holy One for transgressors, the blameless One for the wicked, the righteous One for the unrighteous, the incorruptible One for the corruptible, the immortal One for them that are mortal. For what other thing was capable of covering our sins than His righteousness? By what other one was it possible that we, the wicked and ungodly, could be justified, than by the only Son of God? O sweet exchange! O unsearchable operation! O benefits surpassing all expectation! that the wickedness of many should be hid in a single righteous One, and that the righteousness of One should justify many transgressors!
