When a choir is discordant, there has only to be one voice that knows the correct pitch, and sings it clearly, and the other voices will recognize its veracity and harmonize with it.
Our Lord is the fundamental, is he not? And his Church Militant resounds with him.
And when the fundamental sounds and resounds, then does every string that's attuned ineluctably echo him, and the song is magnified in the communion of saints and angels throughout every manse of the Lord. However measly a string you may be, you sing with his voice, come forth, come forth.
So seek consolation in the communion of saints. Ask frequently the intercession of your guardian angel. Resolve yourself, and pray for hope, knowing how the others dimly recall the song, and having faith, be touched by the immensity of the grace which streams around you.
