Catena Aurea on John 9:35–41: Augustine of Hippo

First, He washes the face of his heart. Then, his heart’s face being washed, and his conscience cleansed, he acknowledges Him as not only the Son of man, which he believed before, but as the Son of God, Who had taken flesh upon Him: And he said, Lord, I believe. I believe, is a small thing. Wouldest thou see what he believes of Him? And falling down, he worshipped Him. (Vulgate)
