For the third time a voice from heaven, from the Heavenly Father, resounds over the Son of Man. The first time it was heard at the baptism in the Jordan, Mt 3:17; Mk 1:11; Lk 3:22.
The second time was on Tabor, Mt 17:5; 2 Pet 1:17-18; Lk 9:35. The third time is now.
At the beginning, middle, and end of Christ’s ministry, the Heavenly Father bears witness to the significance of the Son.
Frivolity may say that “unclear thought mistook the thunder that struck the senses for the voice of God” (De Bette, Stud. und Krit. 1834, 4, 939).
On the contrary, the historian and eyewitness firmly says that this was a voice from heaven, articulate and clear.
He also states what the opinions of spiritually undeveloped people about this matter were: “The people standing by, who heard it, said that it had thundered. Others said, ‘An angel has spoken to Him.’”
The latter opinion deserves special notice, though De Bette entirely overlooks it. Even among the people there were some who distinguished articulate signs, words, in the heavenly voice.
They therefore did not regard it as mute thunder or a dull rumble.
If the other apostles, besides John, had not understood the voice along with the people, the exact historian would have said so. He is not ashamed to display the apostles’ lack of understanding where it occurred.
Therefore it must be accepted as certain that not John alone, but all the apostles, heard and understood the heavenly voice as John transmits it.
Finally, one must not forget that the Apostles Peter and Paul heard a voice from heaven, articulate signs (Acts 9:7; Acts 22:7, 10; Acts 13:15). Later many saints also heard such voices, for example St. Polycarp (Ep. de mart. Polycarpi § 9).
“I have glorified it, and I will glorify it again.” The Heavenly Father embraces His whole relation to the Son, in its past and future.
He does not point to some particular manifestation of His will to the Son. Rather, embracing the whole course of events concerning sinful humanity, taken under the protection of the Son of God, He speaks.
He says that the Father’s good pleasure always rests upon the work of the Son, the Redeemer.
“This voice was not for My sake, but for the sake of the people.” At the Jordan the voice from heaven was heard by the Baptist. On Tabor it was heard by the three apostles.
Now it resounds in the hearing of the people, to warn the simple-hearted against participation in the fearful crime being prepared. It also instructs those among the people who, if not now, then later, would attend to the significance of Christ Jesus.
