The pamphlet mentioned on the first page of this tract is alluded to in Napoleon Noel's "History of the Brethren" in the second volume on pages 701 to 721, this tract is listed in the Biblography on page 721. 

It evidently led to what he termed "The Renton Cleavage" though not to be confused with those known as "Renton Brethren" as being one of the fragments of the "London" or "Taylor" Exclusive Brethren. 

Interestingly, it is stated, "It has already been pointed out that if these new teachings (new among us, at least) are correct a necessary conclusion is that we have never been gathered to the Lord’s Name at all!" (The italics here are as those in the pamphlet.) 

This statement is interesting because behind it lies the question as to which one of the many groups of brethren is gathered together to the Lord's name? At least one group thinks they are the one!
