I do not agree with Good Friday sermons that last two and a half hours. You went on for a good hour too long. Make no mistake, whatever flatterers may say, long discourses like that are hard for both listener and preacher.
Three quarters of an hour for an ordinary sermon, one hour and a half for a Good Friday sermon: that is the norm, do not trespass outside it.
Letter to Jean Baptiste Mille, 15 April 1831, EO VIII n 389
Obviously listeners in church had more endurance in those days!
