ACC ~ 1 Peter 2 v22

NO SIN IN HIM. AUGUSTINE: Note that the apostle holds this statement that Christ did no sin sufficient to prove that there was no sin in him. He who did not sin could not have had sin in him. … Certainly the adult man would have committed sin if there had been sin in the infant. Apart from him there is no one who has not committed sin after reaching his majority, and the reason for this is that there is no one who is without sin at the beginning of infancy. AGAINST JULIAN 5.15.57.

NO GUILE ON HIS LIPS. CYRIL OF ALEXANDRIA: Since human flesh became that of the Word of God, its subjection to corruption has come to an end. He put an end to the sickness of loving pleasure. The only-begotten Word of God has not done this for himself, for his motive is not his own pleasure, but obviously he has done it for us. SERMONS 45.9.

HE PAID FOR OUR SINS. THEODORET OF CYR: Christ was nailed to the cross, paying the penalty not for his own sins but paying the debt of our nature. For our nature was in debt after transgressing the laws of its maker. And since it was in debt and unable to pay, the creator himself in his wisdom devised a way of paying the debt. By taking a human body as capital, he invested it wisely and justly in paying the debt and thereby freeing human nature. ON DIVINE PROVIDENCE 10.26.
