Grantham, Thomas, an English Baptist minister of distinction, was born in 1633. He was selected to deliver to Charles II the confession of faith drawn up by the Baptists, and also at a later period to present a remonstrance against persecution, both of which were kindly received by the king, and redress of grievances promised. He was often engaged in public disputations, in which he displayed great logical skill. He also had a long controversy with the Rev. John Connould, vicar of Norwich, who yet remained his friend through life. Among his writings is Christianismus Primitivus, or the Christian Religion in its nature, certainty, excellency, etc., vindicated (Lond. 1678, fol.).Benedict, History of the Baptists, volume 1; Darling, Cyclop.
