As one who often preaches from a transcript, I was cut by Calvin’s comments to the Duke of Somerset about the “little living preaching” done in his kingdom (emphasis mine).
Calvin objected to read sermons. He was a ‘pattern extempore preacher’. He frequently intimated that the power of God could only pour forth most powerfully in extemporary preaching. In a letter to the Duke of Somerset, Calvin commented, ‘I say this to your Highness because there is little of living preaching in your kingdom, sermons there being mostly read or recited.’
