Thus Christmas is a feast of restored creation. It is in this context that the Fathers interpret the song of the angels on that holy night: it is an expression of joy over the fact that the height and the depth, Heaven and Earth, are once more united; that man is again united to God. According to the Fathers, part of the angels’ Christmas song is the fact that now angels and men can sing together and in this way the beauty of the universe is expressed in the beauty of the song of praise. Liturgical song – still according to the Fathers – possesses its own peculiar dignity through the fact that it is sung together with the celestial choirs. It is the encounter with Jesus Christ that makes us capable of hearing the song of the angels, thus creating the real music that fades away when we lose this singing-with and hearing-with.
