"Most Exalted and Serene Prince and Elector! Most Gracious Lord and Master!
With most humble reverence, I kiss your gracious hand and your most valuable gift of your musical compositions, which to the great joy and with feelings of gratitude of us all, were handed to me, with your gracious letter, by your Serene Highness' Privy Councillor, Joannes Rauch. For, is it not a great blessing, not only to the Gregorian Institution of the Munich Seminary, but also to those on whom devolves the direction and management of it, that you so graciously remember them, and present them with a musical treasure so precious!
We, therefore, throw ourselves at the feet of your Serene Highness, and before the Archipiscopal Pastoral Staff, and express as well as it is in our power our most dutiful thanks, with every devotion and reverence, as we are in duty bound to your sovereign clemency for ever.
This memorial of your highest favour shall be permanently preserved in the archives of the Elector's church at Munich, to the everlasting glory of God, to the honour of the Holy Virgin and of the Holy Archangel Michael, and in memory of your gracious condescension.
Moreover, we admire the very great merit of the music of your Serene Highness not only on account of the high position of its composer, but also on account of its very pleasing artistic effect, which has astonished every one, when the music had been carefully examined by all the Gregorian musicians we summoned to try it. We all—not only I, who consider myself the most insignificant, but also the Gregorian disciples—we all pray in deep humility that the kindly blessings of Heaven may for many years support your Serene Highness in your beneficent functions, for the advantage of the Church, and for the consolation of all good people, especially also for the benefit of your dependants, of whom the Gregorian disciples delight in being the most humble. Permit me to recommend especially these, together with myself, your most humble servant, in our deepest reverence, to your most gracious favour and benevolence. We thus continually pray with bended knees, venturing to hope with the most implicit confidence that Heaven's blessing will result to us from the Archipiscopal Mitre and Pastoral Staff, which we humbly reverence with our kisses.
Your Serene Highness'
Most humble Servant,
Gregorius Schilger, Soc. Jesu,
Inspector of the St. Gregorian House.
Munich, August 7th, 1720."
