John Chrysostom — as excerpted in the Catena Aurea on John 8:37-41

“(Hom. liv. 2) He says this, that they might not attempt to answer, that they had no sin. He reminds them of a present sin; a sin which they had been meditating for some time past, and which was actually at this moment in their thoughts: putting out of the question their general course of life. He thus removes them by degrees out of their relationship to Abraham, teaching them not to pride themselves so much upon it: for that, as bondage and freedom were the consequences of works, so was relationship. And that they might not say, We do so justly, He adds the reason why they did so; Because My word hath no place in you.”
