According to a note in a modern hand (folio 1 verso), 'these 53 sermons were written by John Campbell [Minister] of Craiggy in 1671 & 1672'. The first three sermons were connected with a communion service at Irvine, 12 November 1671; the remaining fifty, on Romans, viii, 1-7, form a group delivered between 8 October 1671 and 14 July 1672. Campbell, who appears to have been Minister of Sorn from 1658 to 1684, had been, at the time of composition of these sermons, deprived of his church for attendance at conventicles.
