The sensual and stiff-necked people could not understand what was taking place before them. It was a miracle, great and mysterious.
It was that wondrous gift which the heavenly Teacher had promised before His Ascension, when He said that those who believe in Him “will speak with new tongues” (Mk 16:17).
Now this promise was fulfilled. His disciples began to speak in other, new languages, and they spoke what the Comforter, the Holy Spirit sent down upon them, had taught them.
Every miracle directed toward lofty religious and moral aims first has in view the removal of natural obstacles to that aim. So it was now.
The teaching of Christ had to be preached to all the nations of the earth. Yet a barrier separated them in the form of different languages and dialects.
The gift of tongues removed this barrier, and the word of Christ could freely spread throughout the whole world.
As a miraculous gift, it was incomprehensible not only to the ignorant crowd of that time. It will remain such even for the highest scientific knowledge, and all scientific attempts to explain it are nothing but vague conjecture.
Some interpreters, among others, have thought to explain this miracle by attributing it chiefly to the hearers.
They suppose that the Apostles spoke in their usual language, but that the hearers, under the impression of the extraordinary phenomena and enthusiasm, imagined that each heard his native tongue.
Or they suppose that, by the action of the Holy Spirit, the Apostles received back the pure, primordial, universally intelligible language lost at the building of the tower of Babel.
This language, they say, was now understood by all nationalities. But under such an explanation, the phenomenon remains perhaps even more miraculous and mysterious.
As for other free-thinking interpreters, who do not acknowledge the gift of tongues as a miracle, they try to explain it naturally.
They point to certain cases of somnambulism, when those subject to it suddenly began, in ecstasy, to speak words and speeches previously unknown to them.
Since this explanation attributes the miracle to an abnormal condition, it is obviously not new. It is only a modified repetition of the explanation given by interpreters contemporary with the phenomenon.
They blasphemously mocked and said, “They are filled with sweet wine.” No, neither sweet wine nor somnambulism was at work in the Apostles.
The wisdom of God was at work in them, clothing them with superhuman power.
Meanwhile the rumble of exclamations spread more and more through the masses of the people, who did not know how to explain the miraculous phenomenon.
But amid the cries of wonder, the mocking voices of blasphemers began to be heard more loudly. They tried to give dominance to their frivolity.
The moment was terrible. The work of God was threatened with general ridicule. But it is never mocked.
At that moment the Apostle Peter stepped forth from among the Apostles and addressed the agitated crowd with a loud voice. “Men of Judea and all who dwell in Jerusalem!” he cried out.
The crowd, struck by the Apostle's courage, fell silent and held its breath. The Apostle Peter continued: “Let this be known to you, and give heed to my words.
For these are not drunk, as you suppose, since it is the third hour of the day.”
