From Preface, Chapter 2, paragraph 2:
It was the manner of those times (whether through men’s desire to enjoy alone the glory of their own enterprises, or else because the quickness of their occasions required present dispatch), so it was, that every particular Church did that within itself, which some few of their own thought good, by whom the rest were all directed. Such number of Churches then being, though free within themselves, yet small, common conference before hand might have eased them of much aftertrouble. But a greater inconvenience it bred, that every later endevoured to be certain degrees more removed from conformity with the Church of Rome, than the rest before had been: whereupon grew marvelous great dissimilitudes, and by reason thereof, jealousies, heartburnings, jars and discords amongst them. Which notwithstanding might have easily been prevented, if the orders which each Church did think fit and convenient for itself, had not so peremptorily been established under that high commanding form, which tendered them unto the people, as things everlastingly required by the law of that Lord of Lords, against whose statutes there is no exception to be taken. For by this mean it came to pass, that one Church could not but accuse and condemn another of disobedience to the will of Christ, in those things where manifest difference was between them; whereas the self same orders allowed, but yet established in more wary and suspense manner, as being to stand in force till God should give the opportunity of some general conference what might be best for every of them afterwards to do; this I say had both prevented all occasion of just dislike which others might take, and reserved a greater liberty unto the authors themselves of entering into farther consultation afterwards. Which though never so necessary they could not easily now admit, without some fear of derogation from their credit; and therefore that which once they had done, they became for ever after resolute to maintain.
