“ Only to Ball does he seem to have frankly bared his mind, and Ball's admiring delineation of him furnishes a singular picture of cautious astuteness and constitutional reserve. It is clear that his heart was firmly set on the propagation of the calvinistic theology; his posthumous works (edited by Richard Sibbes, John Davenport, Thomas Ball, and partly by Thomas Goodwin, D.D. [q. v.] ) are a storehouse of argument in its favour. ”
