Maybe this will help:
Work .... work .... work ..... work .... write book organizing and elaborating on all that earlier work.
You see, it was Newman speaking, lecturing, and writing tracts, even prior to the anti-Catholic laws being repealed in 1828 that upset those in the nobility who didn't like the ideas Newman was popularizing among the clergy and church hierarchy because they included a lesser role for the nobility. That's exactly why the Crown and nobility were anxious to revive old and well worn anti-Catholic lies and slanders and popularize them again since they couldn't stop the repeal of the anti-Catholic laws. They were quite happy with having the Anglican Church under their thumb and hoped that by slandering the Catholic Church once again they would stop Newman and those who agreed with him in their tracks. They were trying to keep the idea of the Anglican Church needing to return to it's roots and original doctrines from becoming an acceptable and popular topic of discussion.
Newman was the focus of what came to be called, “The Oxford Movement”, because he was lecturing and writing tracts. He didn't incorporate "The Oxford Movement, Inc." and only then start printing tracts or little books to put in doctor's waiting rooms. He was already writing the tracts and lecturing before the anti-Catholic laws were repealed and as his tracts became popular a great many people became began to ask why the Anglican Church had modified so much of it's original teaching. I know it's a difficult concept, but Newman worked for years before he wrote a book that combined, organized, elaborated on his lectures that had not been published as tracts, and so on, all in a single book.
Apparently the sort of folks who dig up and try to re-animate long dead anti-Catholic writers aren't familiar with the concept of prolonged effort culminating in a compilation and elaboration of that prolonged effort. Nor are they familiar with the concept of someone trying to close the barn door before the horse gets out which is what Faber and others were trying to do as soon as the anti-Catholic laws were repealed.
