Apringius of Beja — on Rev 4:5 (TRACTATE ON THE APOCALYPSE 4:5)

“He desires that we understand that the entire original preaching of the apostles and indeed the heavenly and sacred doctrine proceeds from the judgment and inspiration of God. We interpret therefore the flashes of lightning to be the words of all the saints, and likewise the thunder to be the voices of the preachers. We confess that all these things come forth from one source, namely, God. Concerning these flashes of lightning and sounds of thunder, it is said: "The voice of your thunder was in the whirlwind; your lightnings illumined the whole world."”
