Augustine of Hippo — as excerpted in the Catena Aurea on John 18:3-9

“(Tr. cxii) They had heard at the first, I am He, but had not understood it; because He who could do whatever He would, willed not that they should. But had He never permitted Himself to be taken by them, they would not have done indeed what they came to do; but neither would He what He came to do. So now having shewn His power to them when they wished to take Him and could not, He lets them seize Him, that they might be unconscious agents of His will; If ye seek Me, let these go their way.”
