II. How great was Pilate's crime in allowing himself to be led astray by the Jews
Accordingly, permitting the infliction on Himself of all that the people's fury inflamed by the priests dared do, He is brought to Annas, father-in-law to Caiaphas, and thence Annas passes Him on to Caiaphas: and after the calumniators' mad accusations, after the lying falsehoods of suborned witnesses, He is transferred to Pilate's hearing by the delegation of the two high-priests, who in neglecting the Divine law, and exclaiming that they had “no king but Cæsar,” as if they were devoted to the Roman laws, and had left the whole judgment in the hands of the governor, really sought for an accomplisher of their cruelty rather than an umpire of the case.
For they gave up Jesus, bound in hard bonds, bruised by many buffets and blows, spat upon, already condemned by their shouts: so that amidst so many signs of their own verdict Pilate might not dare to acquit One Whom all desired to perish. In fact, the very inquiry shows both that he found in the Accused no fault and that in his judgment he did not adhere to his purpose: for as judge he condemns One Whom he pronounces guiltless, invoking on the unrighteous people the blood of the Righteous Man with Whom he felt by his own conviction, and knew from his wife's dream, he must have nothing to do.
That stained soul is not cleansed by the washing of hands, there is no expiation in water-besprinkled fingers for the crime abetted by that wicked mind. Pilate's fault is indeed, less than the Jews' crime; for it was they that terrified him with Cæsar's name, chode him with hateful words, and drove him to perpetrate his wickedness. But he also did not escape incrimination for playing into the hands of those that made the uproar, for abandoning his own judgment, and for acquiescing in the charges of others.
