Our filthiness deserves that God should hold it in abhorrence, and that all the angels should spit upon us; but Christ, in order to present us pure and unspotted in presence of the Father, resolved to be spat upon, and to be dishonoured by every kind of reproaches. For this reason, that disgrace which he once endured on earth obtains for us favour in heaven, and at the same time restores in us the image of God, which had been not only stained, but almost obliterated, by the pollutions of sin.
