At Vespers for the Feast of St Ephrem the Syrian (January 28). Source.
WHEN thou hadst beheld, as in a mirror (2 Cor 3:18), the beautiful things of Paradise, and delighted abundantly in its unspoiled meadows, thou madest the knowledge of God to blossom in the world; and when we partake of it, through the spiritual disposition of our souls, we bloom again in spirit.
Song of Songs 2:10-13.
MY beloved spake, and said unto me, Rise up, my love, my fair one, and come away. For, lo, the winter is past, the rain is over and gone; The flowers appear on the earth; the time of the singing of birds is come, and the voice of the turtle is heard in our land; The fig tree putteth forth her green figs, and the vines with the tender grape give a good smell. Arise, my love, my fair one, and come away.
Frédéric Chopin, Prelude No. 5 (“Raindrop”).
Played by Hélène Grimaud.
