[1] His Puritanism was moderate: he had scruples about vestments, and strong views about such abuses as non-residence, but was more concerned for the substance of religion and the co-operation of all religious men within the Church than for theories of ecclesiastical government.
His name, 'Richardus Grenham,' is appended with twenty-one others to the letters (3 July and 11 Aug. 1570), asking Lord Burghley, the Chancellor, to reinstate Thomas Cartwright in his office as Lady Margaret's divinity reader.
He used to still preach at St Mary's, Cambridge, where he reproved young divines for engaging in controversies, as tantamount to rearing a roof before laying a foundation.
During a period of dearth, when barley was ten groats a bushel, he devised a plan for selling corn cheap to the poor, no family being allowed to buy more than three pecks in a week.
He cheapened his straw, preached against the public order for lessening the capacity of the bushel, and got into trouble by refusing to let the clerk of the market cut down his measure with the rest.
On the appearance of the Marprelate tracts (1589) he preached against them at St. Mary's, on the ground that their tendency was 'to make sin ridiculous, whereas it ought to be made odious.'
He resigned his living about 1591, having held it for about twenty years—he told Warfield, his successor, 'I perceive noe good wrought by my ministerie on any but one familie.'
In 1592 (if Marsden is right) appeared his 'Treatise of the Sabboth,' of which Thomas Fuller says that 'no book in that age made greater impression on peoples practice.'
