1 After that His persecutors had, through the treason of Judas, taken and bound the Lord, who loved us, and gave Himself for us, and whom the Father spared not, but gave Him up for us all: that we may understand that there was no praise due to Judas for the usefulness of his treachery, but damnation for the willfulness of his wickedness: “They led Him,” as John the evangelist tells us, “to Annas first.” Nor does he withhold the reason for so doing: “For he was father-in-law to Caiaphas, who was the high priest that same year. Now Caiaphas was he,” he says, “who gave counsel to the Jews, that it was expedient that one man should die for the people.” And properly enough Matthew, when wishing to say the same in fewer words, tells us that He was led to Caiaphas; for He was also taken in the first place to Annas, simply because he was his father-in-law; and where we have only to understand that such was the very thing that Caiaphas wished to be done.
