Composed for 22 August 1723 in Leipzig, cantata BWV 25 is an example of the magnificent compositions with which Bach, as the new Thomascantor, impressed and challenged his audiences. With its medical metaphors, it is also a potent reminder of the all-pervasive nature of illness and disease in baroque times; their notorious equation with guilt and sin as well as the related ostracism of the sick was not solely a theological notion of the era.
