55. Lastly, in the Gospel the brothers of the Lord were called Sons of Thunder; and when the voice was uttered of the Father, saying, “I have both glorified it and will glorify it again,” S. John xii. 28. the Jews said that it thundered on Him. For although they could not receive the grace of the truth, yet they confessed unwillingly, and in their ignorance were speaking mysteries, so that there resulted a great testimony of the Father to the Son. And in the Book of Job, too, the Scripture says: “And who knows when He will make the power of His thunder?” Job xxvi. 14 [LXX.]. Certainly if these words pertained to the thunders of the heavens, he would have said that their force was already made, not about to be made.
