In the Gospel of John, there are a number of times when Jesus uses the statement "I Am," which his followers would have automatically linked to the divine Name. Some of these statements - Christ as the Bread of Life, the Gateway, the Light of the World - are referenced in Quinn’s text, as well as the Alpha and Omega. The verses may be sung by a cantor or the choir. There are a number of musically effective ways to use this piece in liturgy: with the full choir, as written; simply, with cantor and assembly; or with a two-part refrain, using only the soprano and tenor lines.
