Though holding a position in most of his works that can be described as clearly Particular Baptist and thus Calvinistic, Richardson in his last work expressed a form of eschatological universalism. Richardson wrote:   To Richardson have also been ascribed tentatively "An exact and full Relation of all the Proceedings between the Cavaliers and the Northamptonshire Forces at Banbury", January 1643–4, signed R. S.; "The King's March with the Scots, and a List of the 3 Lords, … that submit to the Parliament upon the surrender of Newark", London, May 1646; and "Oxford agreed to be surrendered to Sir Thomas Fairfax", London, June 1646.
