From the earliest church, Christians adopted ceremonial benedictions into their liturgical worship, particularly at the end of a service. At the time of the Reformation, Protestants abandoned many of the benedictions of the Roman Catholic Church, including the Apostolic Benediction made by the Pope and his delegates, the "last blessing" of the dying, and virtually all benedictions of inanimate objects. A common form of benediction in Baptist and liturgical Protestant churches is for the worship leader to raise his hands and recite the words of the biblical Priestly Blessing (Numbers 6:23-27). This addition to the mass was made by Martin Luther in his Deutsche Messe and remains traditional in Lutheran Churches.
In today’s day and age there are TONS of sung benedictions to choose from. My personal favorite is set to the tune Edelweiss from “The Sound of Music”. I grew up singing this in the chapel where my Gramp was pastor and a copy of it hung on my Grandparents fridge. But, alas, it is not in public domain and violates copyright law. Look it up on the internet. The text is very sweet. I’ve chosen a beautiful setting for us by American composer, musician, writer and music professor Mark Schweizer. The choir has taken advantage of his talent and performed quite a few pieces from his vast catalogue of repertoire. He is a talented writer and writes very well for the voice. In addition, he has a great sense of humor and is the author of the St. Germaine mystery series: The Alto Wore Tweed, The Baritone Wore Chiffon, The Tenor Wore Tapshoes, The Soprano Wore Falsettos, The Bass Wore Scales, The Mezzo Wore Mink, The Diva Wore Diamonds, The Organist Wore Pumps, and The Counterfeit Wore Garlic. The music nerd in me just can’t get enough of these types of stunts.
