A full discovery and confutation of the wicked and damnable doctrines of the Quakers. : As also, a plain vindication and confirmation of sundry fundamental points of the Christian religion, denyed or corrupted by the enemies of the truth in these times. Published for the benefit of such weak Christians, who are not so able to discover and oppugne the dangerous doctrines of subtil seducers when coloured over with fair words and pretences, and so are more apt to be taken in their snares. Whereunto is annexed an excellent discourse proving that singing of Psalmes is not only lawful, but an ordinance of God. / By Jonathan Clapham, a servant of Christ in the work and labour of the Gospel at Wramplingham in Norff.
