Here’s the money quote in my opinion:
As chancellor it was his duty to enforce the laws against heretics and, by doing so, he provoked the attacks of Protestant writers both in his own time and since. The subject need not be discussed here, but More’s attitude is patent. He agreed with the principle of the anti-heresy laws and had no hesitation in enforcing them. As he himself wrote in his “Apologia” (cap. 49) it was the vices of heretics that he hated, not their persons; and he never proceeded to extremities until he had made every effort to get those brought before him to recant. How successful he was in this is clear from the fact that only four persons suffered the supreme penalty for heresy during his whole term of office. More’s first public appearance as chancellor was at the opening of the new Parliament in November, 1529. The accounts of his speech on this occasion vary considerably, but it is quite certain that he had no knowledge of the long series of encroachments on the Church which this very Parliament was to accomplish. A few months later came the royal proclamation ordering the clergy to acknowledge Henry as “Supreme Head” of the Church “as far as the law of God will permit”, and we have Chapuy’s testimony that More at once proferred his resignation of the chancellorship, which however was not accepted. His firm opposition to Henry’s designs in regard to the divorce, the papal supremacy, and the laws against heretics, speedily lost him the royal favour, and in May, 1532, he resigned his post of Lord Chancellor after holding it less than three years. This meant the loss of all his income except about 100 pounds a year, the rent of some property he had purchased; and, with cheerful indifference, he at once reduced his style of living to match his strained means. The epitaph he wrote at this time for the tomb in Chelsea church states that he intended to devote his last years to preparing himself for the life to come.
