Cursed is the man that doeth the work of the Lord carelessly. (Jer. 48:10)
You have begun to sing in the choir; therefore, you glorify the Lord in the image of the heavenly hosts, who ceaselessly sing praise to the glory of their Creator and Lord. How fortunate you are! But do you acknowledge the full sacredness and importance of this godly work, which incomparably more than any other work is worthy to be called godly work? If not, then it is not superfluous to remind you of the threatening and terrible words of the Prophet: Cursed is the man that doeth the work of the Lord carelessly (Jer. 48:10). You see to what a terrible accountability those are liable who negligently and carelessly perform the work of serving God. The chanter (or singer) is the mouth of the Church, i.e., of the society of believers who are praying in church; while singing prayers and hymns, he pronounces them not only for himself, but in the name of all who are present in church, and as all who are praying pronounce their prayers through the mouths of the singers, these last also are the mouth of the Church. Chant unto our God (Ps. 46:7), the Holy Church invites them, but chant ye with understanding (Ps. 46:9). Consider and take heed: of Whom do you sing, to Whom do you pray, before Whom do you stand?
You stand before the One before Whom the angelic ranks stand and walk with fear, covering their faces! You sing praises to the One of Whom all the heavenly powers ceaselessly proclaim: Holy, Holy, Holy, Lord of Sabaoth! Understand how high the work of the chanter is. Understand and admire the mercy of God, Who allows even earthly sinners to bring praise to Him! This heavenly work is the work of an angel and not of a man having unclean lips, as the holy Prophet Isaiah expressed, having heard heavenly singing: Woe is me, for I am pricked to the heart; for being a man, and having unclean lips, I dwell in the midst of a people having unclean lips (Is. 6:5). And you, infirm, weak, and sinful, have been entrusted with such a great work.
