This week the ancient Latin poem, ‘Ubi caritas et amor,’ features twice in the service. This text, based on 1 John 4:16 and thought to have been written before the tenth century, was from the Middle Ages one of the antiphons on Maundy Thursday, where it illustrates the “new commandment” that we love another (John 13:34). Sunday’s offertory is a modern setting of the Latin text, written by the English composer Alan Bullard, a student of Herbert Howells. Set for two sopranos and organ, it is sung by Lauren Hauser and Megan Sharp. The second setting is a congregational hymn, “Where Charity and Love Prevail,” which is an English translation of ‘Ubi caritas’ by Omer Westendorf (1916-1997), a Catholic composer and hymn writer.
