This is a description by the Revd Dr Donald MacEwan, Chaplain to the University of St Andrews, of a Chapel service during the 2015 Choral Summer School devised by him, drawing upon a service in the Thomaskirche in Leipzig when Cantata No. 78 by J S Bach was part of the service. The liturgy included parts of this cantata and other Lutheran music, such as a sung Creed and a chorale. Holy Communion was celebrated and a sermon in the style of the original was preached by the Chaplain, from which excerpts are given.
