A copy of a letter written by Mr. Stephen Marshall [electronic resource] : to a friend of his in the city, for the necessary vindication of himself and his ministry, against that altogether groundlesse, most unjust, and ungodly aspersion cast upon him by certaine malignants in the city, and lately printed at Oxford, in their Mendacium Aulicum, otherwise called Mercurius Aulicus, and sent abroad into other nations to his perpetuall infamy. In which letter the accusation is fully answered. And together with that, the lawfulnesse of the Parliaments taking up defensive arms is briefly and learnedly asserted and demonstrated, texts of Scripture cleared, all objections to the contrary answered, to the full satisfaction of all those that desire to have their consciences informed in this great controversie.
