John Chrysostom — as excerpted in the Catena Aurea on John 9:1-7

“(Hom. liv. 2) That the glory of God should be made manifest, He saith of Himself, not of the Father; the Father’s glory was manifest already. I must work the works of Him that sent Me: i. e. I must manifest Myself, and shew that I do the same that My Father doeth.”
