“Sound the trumpet at the new moon,” says David, “even in the notable day of your feast” (Psalm 80:3).
The commandments of Divinely-inspired teaching are assuredly a law for those who hear them.
Therefore, since the notable day of our feast is at hand, let us, too, fulfill the law and become heralds of the solemnity.
The trumpet of the law, as the Apostle bids us understand, is the word.
[…] So let us produce a clear and audible sound, brethren, one that is no less noble than that of the trumpet.
