ACC ~ John 12 v29

GOD DOES NOT SPEAK WITH THE VOICE OF THE BODY

AMBROSE: How does God speak? Is it with the voice of the body? Not at all. He utters oracular words with a voice that is far more significant than is the voice of the body. The prophets heard this voice. It is heard by the faithful, but the wicked do not comprehend it. And so, we find the Evangelist in the Gospel listening to the voice of the Father speaking: “I have glorified it and will glorify it again.” But the Jews did not listen, which is why they said, “It has thundered.” … Here is an occasion when he was heard speaking, whereas to some people he did not speak. ON PARADISE 14.69. [1]

WHEN ANGELS SPEAK

GREGORY THE GREAT: When God speaks audibly, as he does here, but no visible appearance is seen, he speaks through the medium of a rational creature, that is, by the voice of an angel. MORALS ON THE BOOK OF JOB 28.1.4. [1]
