 We just heard Mozart's setting of the Ave Verum Corpus, which is a Latin hymn from the 13th century, which he, during the high Renaissance, set to music. The translation is, Hail true body, born of the Virgin Mary, truly suffered, sacrificed on the cross for mankind, from whose pierced side flowed blood and water, be for us a foretaste of the heavenly banquet in the moment of our death.
