Thirty years ago, the predominate vestment of Protestantism was the cassock and surplice: the cassock being a black robe, buttoning down the front, and the surplice being a full white vestment which comes down to the knees. These two vestments were used together for nearly all Lutheran worship services. Today however almost no one wears them and I would like to ask the question "why?"
Indeed, some of our more apt readers will be able to point out that certain individuals, namely Luther D. Reed himself, advocated for the discontinuation of the use of the cassock and surplice. Why would we want to bring back into use vestments which were considered antiquated thirty or forty years ago? Those who pose this question miss the point of why Dr. Reed advocated their discontinuation – this reason being that the cassock and surplice was being used in place of the alb for all services including mass.
Dr. Reed won his argument in the long run, and I am happy for it. Today we see worship leaders – laity and clergy – using the alb every Sunday for worship, regardless of whether it is Mass or the Office. But if we look at the proper use of the cassock and surplice, we may find some light on the subject of both why Dr. Reed which to put it away, and why I would like to see more of its use. And I don't think Dr. Reed and I are at odds.
The cassock and surplice properly can be used at any occasion – namely the Office – outside of Mass. So for Morning Prayer, Evening Prayer, and any of the other hours observed. The alb is properly used in Mass. This is rules set out by Roman Cannon and so observed by our Roman Catholic brothers in the priesthood, and is laid out as good liturgical practice by Ms. S. Anita Stauffer in her book Altar Guild and Sacristy Handbook, published by Augsburg Fortress.
The cassock and surplice has room to survive today along side with the alb, yet its continuing decline of use is indicative of the continuing decline of the worship form of the Office. Both the Office and Mass has good value in today's worship world; both the cassock and surplice and the alb have room together in today's worship world.
