Luke 8:46

Which of you, &c. This is to anticipate an objection of the Jews. For they might say, "We do not believe thee, because thou art a violater of our law, in healing the sick on the Sabbath-day." Produce any other charge against Me, and I will submit to your disbelieving Me. My healing on the Sabbath was not a violation, but a sanctification of the Sabbath. I leave any further charge to be decided by you who are my sworn enemies. So confident was Christ in His innocence that no one could lay anything to His charge which bore the slightest resemblance to sin. For He was Himself sinless, both on account of the Beatific Vision which He enjoyed, as the Blessed in heaven are incapable of sin for the same reason (for seeing God to be the Supreme Good, they necessarily love Him with all their strength, and hate whatever displeases Him) and likewise from the hypostatical union with the Word. For because His humanity existed in the Person of the Word, the Word kept His humanity free from all sin, and in perfect holiness. For if the humanity of Christ had sinned, the Person of the Word would have sinned; which is impossible. For virtuous or vicious actions relate to persons, and are attributed to them. Hence S. Ambrose (on Ps. xl. 13) brings in God the Father thus addressing Christ, "Thou wert conversant with sinners, Thou didst take on Thee the sins of all, Thou wast made sin for all, but yet no practice of sin could reach Thee. Thou didst dwell among men, as if among angels, Thou madest earth to be like heaven, that even there also Thou mightest take away sin."

If I say the truth, &c. He here shuts out another objection of the Jews. For they could have said, We believe Thee not, not for any sin which Thou hast committed, but because the things Thou sayest and teachest are not true." Christ meets the. objection by saying, "I have proved to you My doctrine by so many arguments and miracles, that no prudent person who is not blinded by hatred could question its perfect truth. If then My life is most innocent, and My doctrine most true, why do ye not believe Me?" Receive then the truth not as a bare assertion, but as demonstrated by reason.
