Henry wanted to marry Anne Boleyn, and hence started the Reformation. He dumped poor Catherine, got married and made his own church with the help of Anne, and had Elizabeth who went on to become the greatest queen evah! And then he executed poor Anne and broke all the monasteries. This is the Reformation. Alright, I am simplifying it, but after hearing so many versions of the above, I am often left pulling out my hair. There are just so many things wrong with this.
Without the divorce there would therefore have been no Reformation, which is not at all the same thing as to say that there was nothing to the Reformation but the divorce.
