Reformation not separation: or, Mr. Crofton's plea for communion with the church : under those corruptions, and by that disorderly ministration to which he cannot conform, nor by it administer. In a letter, written July 20. 1661. in, and from the Tower of London, to R.S. to satisfie the weak, and silence the wicked, who insulted in, or were offended at his endeavoured (and clamorously reported as obtained) attendance on Gods publick worship in that place, during his confinement. Now published, to silence censures and calumnies, satisfie such who would walk uprightly in this houre of temptation. By the said R.S. to whom it was written. Unto which, is added the copy of another letter, written on the same occasion and subject.
