A letter to Sir H. Mackworth, concerning his treatise about the late occasional bill [electronic resource] : Upon four heads especially. I. Whether all wise Nations in the World do preserve the Administration of Publick Affairs in Persons of one and the same Perswasion, in Matters of Religion. II. Whether the Admission of any into Imployments, other than Sincere Members of a National Church, be consistent with the Safety of the Establish'd Government. III. Whether Occasional Communion with the Church, and abiding Nonconformity, are Contradictions. IV. Whether Dissenters do not still need, in several Instances, to be convinced by the Author, of the Usefulness and Necessity of such a Bill, for their own Good. By John Lacy, Esq;.
