The principles, or, the patterne of wholsome words : Containing a collection of such truths as are of necessitie to be beleeved unto salvation, separated out of the body of all theologie: made evident by infallible and plaine proofes of Scriptures. And withall, the seueral uses such principles should be put to are abundantly shewed. A project much desired, & of singular use for all sorts of Christians. By N. Byfield, preacher of Gods Word at Isleworth in Middlesex.
